Severe Weather Awareness Week in New York and Pennsylvania
April 24th through April 30th, 2016
The week of April 24th through April 30th, 2016 has been declared Severe Weather Awareness Week in New York and Pennsylvania.
NOAA's National Weather Service joins in partnership with the state agencies of both New York and Pennsylvania, local agencies, volunteer agencies and private sector organizations in urging all residents to learn how to protect themselves from the hazards of flooding,tornadoes and severe thunderstorms.
Severe Weather Awareness Week is a time to learn more about thunderstorms, tornadoes, lightning and flooding and prepare for the dangers they bring to New York and Pennsylvania during the warmer part of the year.
As part of Severe Weather Awareness Week, National Weather Service offices will conduct a test warning on Thursday April 28th at 1:15 pm in New York state only. There will be no test warning in Pennsylvania.
These drill warnings in New York provide emergency management agencies, schools hospitals, nursing facilities, the media and the public an opportunity to test communications systems, practice and update safety procedures and review severe weather terminology.
Each day next week the focus will be on a different topic, with an emphasis on weather safety and preparedness. Below are the topics that will be covered.
Plan ahead for the hazards that thunderstorms create. Help us make severe weather awareness week a success, by being prepared.

This is the first of a five part series on severe weather safety which will run each day during New York and Pennsylvania's severe weather awareness week.
This week, April 24th through April 30th, has been declared Severe Weather Awareness Week in both New York and Pennsylvania. NOAA's National Weather Service joins in partnership with the state agencies of both New York and Pennsylvania, local agencies, volunteer agencies, and private sector organizations in urging all residents to learn how to protect themselves from the hazards of flooding, tornadoes, and severe thunderstorms.
Over the last 10 years severe thunderstorms, tornadoes and flash floods have killed 51 people in New York and Pennsylvania and caused many millions of dollars in damage. The National Weather Service in Birmingham has issued nearly 2000 warnings for severe thunderstorms, tornadoes and flash floods since 2006. To reduce your chances of being killed or injured by severe weather, it is important to understand the meaning of severe weather watches and warnings.
Severe thunderstorms: are defined as those thunderstorms that produce winds of 58 mph or greater and or hail of one inch in diameter or larger. A severe thunderstorm watch means that severe thunderstorms are possible over the next several hours, typically no more than six hours. You should continue with your daily routine, but be prepared to move to a place of safety should a severe thunderstorm warning be issued. A severe thunderstorm warning means that severe thunderstorms are imminent or occurring. A warning implies a significant threat to life and property. You should seek shelter immediately when a severe thunderstorm warning is issued.
Tornadoes: are violently rotating columns of air in contact with the ground and attached to the cloud base above. Like a severe thunderstorm watch, tornado watch means that tornadoes are possible over the next several hours again usually no more than six hours. A tornado warning means that a tornado is imminent or occurring. A tornado warning implies an immediate threat to life and property. Take shelter immediately.
Flash flooding: is a rapid rise, within six hours, of water along a stream or low lying urban area. The most common cause of flash flooding is heavy downpours associated with thunderstorms. A flash flood watch means that conditions are favorable for flash flooding. Continue with your daily activities, but be prepared to head to a place of safety should a flash flood warning be issued. A flash flood warning means that flooding is imminent or occurring. Flood waters can rise rapidly. Seek shelter immediately when a flash flood warning is issued.
NOAA Weather Radio offers the best way to stay in touch with dangerous weather conditions 24 hours a day and 7 days a week, whether at home, work or play. NOAA Weather Radio provides continuous broadcasts of weather information, with immediate relay of any severe weather warnings. NOAA's National Weather Service recommends everyone have access to a NOAA Weather Radio.

This is the second of a five part series on severe weather safety which will run each day during New York and Pennsylvania's severe weather awareness week.
Today we discuss what classifies a thunderstorm as severe, and what the differences are between a severe thunderstorm watch and a severe thunderstorm warning. We also give you information on what to do when a watch or warning is issued for your area.
What is a severe thunderstorm?
A severe thunderstorm is any thunderstorm that produces wind gusts of 58 miles an hour or higher, and or hail one inch in diameter or larger. Those hailstones are about the width of a quarter. Severe thunderstorms are often accompanied by torrential downpours and frequent cloud to ground lightning. They occasionally produce tornadoes with little or no advance warning. Sometimes very strong winds in severe thunderstorms produce damage that people mistake for tornado damage.
What is a severe thunderstorm watch?
A severe thunderstorm watch means severe thunderstorms are possible in and close to the watch area. The watch is issued to alert you to the possibility that thunderstorms with damaging winds and large hail may develop. A watch does not mean severe weather is occurring. The national weather service's storm prediction center issues a watch for many counties and for several hours at a time.
What you should do when a severe thunderstorm watch is issued?
Go about your normal activities, but watch the sky around you for developing storms. Periodically check noaa weather radio, your mobile device or tv and radio stations for updates and possible warnings. Know which county you live in, and which ones border your community. If you are on vacation, or driving through an unfamiliar area, remember the name of the county you are in. Know where you are in relation to other towns or cities. Plan how to get to a safe place quickly if a warning is issued for your area, or if severe weather is observed.
What is a severe thunderstorm warning?
A severe thunderstorm warning means a severe thunderstorm is going to move through your county soon, so you need to take quick action to protect your life and property. Severe thunderstorm warnings are issued by the national weather service when doppler weather radar has detected a severe thunderstorm, or when one has been reported by skywarn severe weather spotters, county emergency officials, the police, or the public. Typically the warning is issued for one or two counties at a time for a period of up to one hour.
What to do when a severe thunderstorm warning is issued?
If you are outdoors, get inside your home, a strong building, or in your car. If there is no building nearby, your best protection is in a cave or ditch. Boaters should head to shore immediately.
When indoors, go to an interior room on the lowest level. Stay away from windows and doors. Do not use electrical appliances.
If you are driving, pull over to the side of the road until the storm passes. Heavy rain with any thunderstorm can flood roads quickly, so never try to drive through an area where water covers the road, even if you think it is shallow. This water may sweep your vehicle away.

This is the third of a five part series on severe weather safety which will run each day during New York and Pennsylvania's Severe Weather Awareness Week.
Today we discuss severe weather preparedness and safety. All thunderstorms, whether they are severe or not, are dangerous due to lightning. When one approaches, you need to protect yourself.
Before a storm, develop a safety plan you can implement to protect yourself and your family at home, school, work or outdoors. Identify a safe place to take shelter and know what actions to take when a warning is issued. The best way to do this is to conduct frequent drills.
Lightning is a thunderstorm's biggest killer. Do not use electrical appliances while a thunderstorm is nearby.
If you are outdoors, seek shelter in a sturdy building. Keep out of open areas such as pavilions or gazebos. Stay away from tall objects such as isolated trees, and metal objects such as towers supporting power lines. Also stay away from wire fences, clothes lines, metal pipes, and rails. If in an automobile, do not touch metal parts or the exterior.
Lightning may be about to strike if you are out in the open and feel your hair stand on end or your skin tingle. Drop onto your tiptoes at once, bend forward and put your hands on your head. Don't lie flat on the ground.
Stay out of the water. If you are boating, head to shore at the first sign of threatening weather. In addition to the danger of lightning, gusty thunderstorm winds can easily capsize small boats.
You should also stay away from places that could flood during a thunderstorm. Flash flooding caused by heavy downpours is another thunderstorm danger. Low lying areas, especially near streams and creeks, can flood rapidly. Never drive your car into a flooded area.
Remember, thunderstorms occasionally produce tornadoes. And sometimes thunderstorm winds are strong enough to cause tornado like damage. So be prepared to move to a safe shelter when a thunderstorm is near.

This is the fourth of a five part series on severe weather safety which will run each day during New York and Pennsylvania's severe weather awareness week.
Today we discuss the difference between a tornado watch and a tornado warning, and give you tips on what to do when a watch or warning is issued for your area.
A tornado is a violently rotating column of air in contact with the ground. The wind speed inside a tornado ranges from under 100 miles an hour to over 200 miles an hour. They can travel as fast as 70 mph, and can destroy virtually everything in their path.
While most tornadoes that occur in central New York and northeast Pennsylvania are not as strong as their counterparts in the Midwest, strong and damaging tornadoes can and do occur here. On May 31st and June 2nd 1998, central New York and northeast Pennsylvania was hit by several tornadoes, some of which had wind speeds up to 150 mph! In July 2014 there was a tornado that killed 4 people in upstate New York. In June of 1998 2 people were killed by a tornado in northeast Pennsylvania.
What does a tornado watch mean?
A tornado watch is issued when conditions are favorable, over a large area, for tornadoes and severe thunderstorms. The tornado watch is issued to alert you to the possibility that severe thunderstorms are expected to develop, and that they may produce tornadoes. The National Weather Service's storm prediction center issues a tornado watch for many counties and for several hours at a time.
What you should do when a tornado watch is issued?
Go about your normal activities, but watch the sky around you for developing storms. Periodically listen to NOAA weather radio, TV and radio stations or check your mobile device for updates and possible warnings.
Know which county you live in, and which ones border your community. If you are on vacation, or driving through an unfamiliar area, remember the name of the county you are in and where you are in relation to other towns or cities. Know how to get to a safe place quickly if a warning is issued for your area, or if thunderstorms approach.
What does a tornado warning mean?
A tornado warning is issued when doppler radar shows a developing tornado, or a when a tornado has been sighted by SKYWARN
spotters, county emergency officials, police, or the public. The warning means a tornado is going to move through your county soon, so you need to take immediate action to protect your life and property. Tornado warnings are issued by National Weather Service offices, typically for a portion of a county, for up to one hour.
What you should do when a tornado warning is issued?
The key is to remain calm, but take immediate action. If you are at home or in a small building, go to the basement or to an interior room on the lowest floor. Closets, bathrooms, and other interior rooms offer the best protection. Get under something sturdy or cover yourself with a mattress.
If you are in a school, hospital, or shopping center, go to a pre-designated shelter area. Stay away from large open areas and windows. Do not go outside to your car. If you are in a high rise building, go to an interior small room or hallway on the lowest floor possible. Do not use the elevator, use the stairs instead.
For the best protection, get under something sturdy or drop to your knees facing an interior wall. Lean forward, with your hands shielding your head.
Get out of mobile homes or vehicles. They are easily tossed about by strong winds in the tornado. Take shelter in a substantial structure. If there is no shelter nearby, lie flat in a ditch or low spot, with your hands shielding your head. Never stay inside the mobile home or vehicle.

This is the fifth of a five part series on severe weather safety which will run each day during New York and Pennsylvania's severe weather awareness week.
Today we discuss flood safety and the differences between a flood watch and a flood warning, and tell you what to do if a watch or warning is issued for your area.
Floods can be deadly!
Floods are the number one killer in the united states among storm related natural hazards. The main cause of death during floods comes from automobiles being swept away by flood waters. Many people die needlessly in floods because they try to cross flooded roadways!
Central New York and northeast Pennsylvania have a long history of floods. Devastating floods are no stranger to central New York and northeast Pennsylvania. In fact, flooding ranks as the biggest threat to many communities in our region. There are many ways that flooding can develop over our area. Stationary thunderstorms caused a major flood in July 1935 and in the Catskills and Poconos in May 2004 and June 2007 respectively. Tropical storms Agnes and Eloise both caused major floods over the area in 1972 and 1975 respectively. Rapid snow melt combined with heavy rainfall resulted in major floods in both January 1996 and April 2005. A tropical feed of moisture parked over the area for several days in June 2006 and caused significant flooding over a large portion of central New York and northeast Pennsylvania. Tropical cyclones Irene and Lee also brought catastrophic flooding to our area in September 2011.
What types of floods are there?
Floods, which occur on small streams and creeks, when heavy rain falls in a short period of time are known as flash floods. They are the deadliest of all floods, and are the most difficult to forecast. Warning times can be very short. Flooding also occurs on our larger rivers and streams. A period of mild winter weather can cause ice on the river to break up, causing ice jam flooding.
What does a flood watch mean?
A flood watch means there is potential for flooding to occur, not that flooding is occurring. The watch is typically issued for several counties at a time, and ideally is issued 6 to 24 hours before flooding is expected. This way you will have enough time to prepare.
Go about your normal activities, but make periodic checks of NOAA weather radio, your mobile device, tv and radio stations for updates and possible flood warnings. Know which county you live in, and where you are in relation to streams, creeks or rivers, which can become killers in heavy rains.
If you live or work in an area which is prone to flooding, have a safe evacuation route to use if flooding occurs. Make sure everyone in your home or office knows where to go if flooding occurs. Have a battery operated radio, and several flashlights available and in working order. Take precautions to secure your property.
What does a flash flood warning mean?
A flash flood warning means rapid life threatening flooding is occurring, or will soon begin. You need to take action immediately to protect your life and property if you are in the danger area.
What you should do when a flash flood warning is issued?
Move to higher ground immediately and get out of the danger area. Never drive across bridges covered with water, or through areas where water covers the roadway. If your car stalls in a flooded or low lying area, abandon it immediately. Rapidly rising flood waters could easily sweep it away. Be especially careful at night, when it is harder to see flooded areas.
What does a river flood warning mean?
A river flood warning means that river levels will exceed flood stage on certain points along our larger rivers, like the Chemung, Susquehanna and Delaware rivers. River floods take longer to develop so they may not pose as much threat to life, but can take a much larger toll on property.
What you should do when a river flood warning is issued?
If you live in a flood plain, be prepared to evacuate if ordered to do so. Make sure you have all necessary items that you would need in the event that you cannot return home for several days. Make arrangements to protect your property by moving your valuables to higher ground, or an upper level of your home.
