Monday

We will explore what precautions you can take to mitigate against New York's harsh winters and how you can become ready and more resilient.

It has been proven that the best way to prepare for extreme weather is to have a plan. Never let a winter storm take you by surprise. If you are expecting to be at home or at work during an extreme winter weather event, you need to be concerned about losing power, heat, or cell / phone service. Losing one of these three services may create a life threatening situation. Make sure you have a back up plan.

Whether you are at home, on the road or at work, one should always have an emergency kit. An emergency kit should include the following: a flashlight and extra batteries, a battery-powered NOAA Weather Radio, food and water, extra prescriptions, an emergency heat source, first-aid supplies and a cell phone.

Home Winter Preparedness

The best action to take during a winter storm is to stay inside and not travel, unless it is an emergency.

If you must drive, slow down and allow extra time to reach your destination! Let someone know where you are going and what route you are going to take. If your car gets stuck in a storm, stay in your vehicle! If you leave your vehicle, you could become disoriented quickly if there is wind-driven snow and cold. Run the motor for a total of 10 minutes each hour for heat. While running the motor, open the window a little bit so that fresh air can get into the car to avoid carbon monoxide poisoning. Make sure you clear snow away from the exhaust pipe to avoid gas poisoning. Attach a bright cloth to your car door to draw attention to yourself, and when it stops snowing, raise the hood of your car to indicate to others you need help.

Car Winter Survival Kit Checklist

Several layers of loose fitting clothing are better than one tight fitting garment. Mittens are warmer than gloves. Do not forget your hat since your body’s greatest heat loss occurs from your head.

Wind chill, the combination of cold temperatures and wind, increases the danger of frostbite or hypothermia. Be especially cautious when venturing out onto an ice covered body of water. An ice thickness of at least four inches is recommended to support a person. Snowmobiles and ATVs need at least six inches of ice, while cars and light trucks require at least eight to 12 inches. Factors which can be used to assess the strength of the ice include the ice appearance, ice thickness, daily average temperature, snow cover and distribution of the load on the ice.

Lake effect snow is a common weather phenomena in the Great Lakes region. Lake effect snow develops mainly in northern, central and western New York during the late fall and winter months. When cold, Canadian air moves over Lakes Ontario and Erie, the relatively warm and moist air from the lakes rise quickly, condenses, and forms lake effect snow.

Lake Effect Snow

The direction of the wind is the most important factor of who will see the lake effect snow. Heavy snow could be falling at one location, while the sun may be shining just a mile or two away in either direction. The Tug Hill Plateau in upstate New York typically sees over 200 inches of snow per year mainly from Lake Effect.

Lake effect snow develops in bands. These bands can produce several feet of snow within a short period of time. From November 17th to 19th, 2014, up to 7 feet of snow fell downwind of Lake Erie just south of Buffalo.

Snow squalls are intense short-lived bursts of very heavy snow. Snow squalls produce blizzard-like or white-out conditions that typically last less than 30 minutes. They produce rapid snowfall accumulations, rapid drop in visibility and flash freeze conditions on our roads. This makes snow squalls very dangerous to motorists. Nationwide, snow squalls can claim hundreds of lives each winter.

Take extreme caution while driving through both lake effect snow and snow squalls. Heavy snowfall in general creates very low visibilities. Lake effect snow and snow squalls can be narrow and intense with visibilities dropping quickly to less than a hundred feet without warning. Lake effect snow and snow squalls often have snowfall rates over 2-3 inches per hour. This leads to very hazardous driving conditions. If all possible, do not drive through intense lake effect snow or snow squalls.

Wednesday

Over the past few winters, powerful snowstorms developed along the east coast and paralyzed cities across much of the northeast. These winter storms disrupted hundreds of thousands of lives ranging from loss of power to transportation difficulties.

Large accumulations of snow can be produced by Nor'easters. Smaller more common snowfall events are often generated by systems called Alberta clippers.

 

Noreaster

 

Nor'easters are intense low pressure systems that track along the eastern seaboard. Its name comes from mariners that experienced the strong northeast winds associated with these storms, but inland they are known for their heavy snow and at times blizzard conditions. Some memorable Nor'easters in recent years include the President's day Snowstorm of 2003, the Valentine's Day Snowstorm of 2007, the Blizzard of 2017, and most recently the December 2020 Snowstorm that produced 40 inches of snow at the Greater Binghamton Regional Airport. Snowfall rates in a Nor'easter can reach up to 3 to 6 inches per hour which can last for several hours.

Alberta clippers are common to our region bringing a quick round of snow. Alberta clippers are low pressure systems that developing or near the providence of Alberta, Canada. Alberta clippers move southeast very quickly and typically bring a few to several inches of snow. Their quick movement limits the snow amounts. Click on image for a larger view.

Ice Storms often cause widespread power outages. Ice accumulations can be extremely slippery for motorists and pedestrians. Bridges and overpasses are particularly dangerous because they freeze before other surfaces.

Friday

This message will provide you with some terms the National Weather Service uses to describe winter weather as well as the definitions of watches, warnings, and advisories issued for winter weather events.

Watches are issued when a storm is in it's early stage of development, and may create conditions that may harm life and property. Hazardous winter weather is only a possibility, not a certainty.

The following are the watch headlines issued for winter weather events:

  • Winter Storm Watch: is issued when heavy snow, damaging ice accumulations, heavy lake effect snow, or blizzard conditions are possible. Winter storm watches are typically issued 36 to 72 hours before a winter storm starts.
  • Wind Chill Watch: is issued when dangerously cold wind chills are possible typically in the next 36 to 72 hours.

Warnings are issued when the threat to life and property is imminent or has already begun from severe winter weather.

The following are the warning headlines issued for winter weather events:

  • Winter Storm Warning: is issued when hazardous winter weather in the form of heavy snow, freezing rain, sleet or any combination there of, is imminent or occurring. Winter storm warnings are typically issued 12 to 36 hours before the event is expected to start.
  • Lake Effect Snow Warning: is issued when heavy lake effect snow is imminent or occurring. Lake effect snow warnings are typically issued 12 to 36 hours before the event is expected to start.
  • Ice Storm Warning: is issued when damaging ice accumulations are expected within the next 12 to 36 hours.
  • Blizzard Warning: is issued when sustained or gusty winds of 35 mph or more prevail, combined with falling or blowing snow, reduce visibilities of one quarter of a mile or less, and last for at least 3 hours.
  • Snow Squall Warning: is issued when a band of very heavy snow is expected to produce snowfall above 2 inches per hour, visibilities less than 1/4 mile for between 15 and 30 minutes. The snow squall could be accompanied by gusty winds, blowing snow and a flash freeze on roads. Snow squall warnings have been expanded to include the enitre state of New York for the upcoming winter.
  • Wind Chill Warning: is issued when the combination of extreme cold and winds occur. This combination will result in frostbite, hypothermia, or even death when exposed in this type of condition for an extended period of time.

Advisories are issued for less serious weather conditions that will not cause immediate threat to life and property. Advisories will be issued when weather conditions will impact motorists, outdoor activities, or public events. These events could become life-threatening if proper precautions are not taken.

The following are the advisory headlines issued for winter weather events:

  • Winter Weather Advisory: is issued for accumulations of snow, lake effect snow, freezing rain, freezing drizzle, or sleet, that will create inconveniences. During an advisory, if caution is not exercised, life and property may be threatened.
  • Wind Chill Advisory: is issued when wind chill temperatures create inconvenience to life with prolonged exposure. If caution is not exercised, hypothermia and frostbite may occur.
