Reports are run once per day, against the past 24 hours of data.

Lightning is the most dangerous and frequently encountered weather hazard that most people experience each year.

It is the second most frequent killer in the United States with nearly 100 deaths and 500 injuries each year.
Floods and flash floods are the number one cause of weather-related deaths in the U.S.

All thunderstorms produce lightning and are dangerous.
Lightning kills more people each year than tornadoes.

Lightning often strikes as far as 10 miles away from any rainfall.
Many deaths from lightning occur ahead of the storm because people try to wait to the last minute before seeking shelter.
You are in danger from lightning if you can hear thunder.
If you can hear thunder, lightning is close enough that it could strike your location at any moment.

Lightning injuries can lead to permanent disabilities or death. On average, 20 percent of strike victims die; 70 percent of survivors suffer serious long-term effects.

Look for dark cloud bases and increasing wind.
Every flash of lightning is dangerous, even the first.
Head to safety before that first flash. If you hear thunder, head to safety!

Blue skies and Lightning... Lightning can travel sideways for up to 10 miles.
Even when the sky looks blue and clear, be cautious. If you hear thunder, take cover.

Weather Facts

HEAT INDEX -
The heat index is an index that combines air temperature and moisture to give an apparent temperature (how hot it "feels"). Hot, humid air "feels" hotter than hot, dry air because the extra moisture in the air slows the evaporation of sweat from our skin. Evaporation of water always produces a cooling effect, since the extra energy needed to convert water from liquid to gaseous water vapor is taken from the air, thus reducing the temperature of the air.
