An Excessive Heat Warning is in effect for the Kern County Deserts until 8 PM PDT Monday evening. An Excessive Heat Warning means that a prolonged period of dangerously hot weather is expected. Heat related illnesses, such as heat exhaustion and heat stroke are possible if simple precautions are not taken. Drink plenty of fluids, stay out of the sun, and remain in an air-conditioned room.
A Heat Advisory is in effect for the San Joaquin Valley, West Side Hills, and Sierra Nevada foothills from 11 AM PDT this morning until 8 PM PDT Monday evening. Heat sensitive people and those who are new to the area will be most prone to heat illness. Dehydration and prolonged exposure or strenuous physical activity outdoors could lead to heat exhaustion and/or heat stroke. If you have to be outside, apply sunscreen, stay hydrated, and wear light colored, loose fitting clothing.
Widespread triple digit heat will impact the Kern County Desert, the San Joaquin Valley, and the adjacent lower foothills Sunday afternoon, resulting in a dangerous risk for heat-related illnesses. Heat-related impacts are possible today for most people if simple precautions are not taken. Plan to take action to reduce time outdoors, drink plenty water, and remain in air-conditioned buildings. Heat-sensitive groups, such as the elderly, young children, and those with chronic ailments may need assistance to avoid heat-related illness. As always, never, ever leave a child or pet in an enclosed automobile.

What is Skywarn?

The effects of severe weather are felt every year by many Americans. To obtain critical weather information, NOAA's National Weather Service (NWS), part of the U.S. Department of Commerce, established SKYWARN® with partner organizations. SKYWARN® is a volunteer program with nearly 290,000 trained severe weather spotters. These volunteers help keep their local communities safe by providing timely and accurate reports of severe weather to the National Weather Service. Although SKYWARN® spotters provide essential information for all types of weather hazards, the main responsibility of a SKYWARN® spotter is to identify and describe severe local storms. In the average year, 10,000 severe thunderstorms, 5,000 floods and more than 1,000 tornadoes occur across the United States. These events threatened lives and property. Since the program started in the 1970s, the information provided by SKYWARN® spotters, coupled with Doppler radar technology, improved satellite and other data, has enabled NWS to issue more timely and accurate warnings for tornadoes, severe thunderstorms and flash floods.

SKYWARN® storm spotters are part of the ranks of citizens who form the Nation's first line of defense against severe weather. There can be no finer reward than to know that their efforts have given communities the precious gift of time--seconds and minutes that can help save lives. While the main role of a storm spotter is to be their community's first line of defense against dangerous storms, they also provide important information to NWS warning forecasters who make critical warning decisions. Storm spotters play a critical role because they can see things that radar and other technological tools cannot, and this ground truth is critical in helping the NWS perform our primary mission, to save lives and property.
