Much of Region 8 in an Excessive Heat Warning

JONESBORO, AR (KAIT) -The National Weather Service has issued an Excessive Heat Warning until 10:00 PM Thursday for many counties in eastern Arkansas.

The weather service says the heat index could top 110 degrees Thursday afternoon, creating a dangerous situation for anyone outside.  The warning means that a prolonged period of dangerously hot temperatures will occur.  The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely.

The weather service asks that you take the following precautions: drink plenty of non-alcoholic fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors as well has pets.

The high for the day should occur around 4:00 PM Thursday, but will not cool below excessive limits until well after dark.  A ridge of high pressure over Region 8 coupled with high dew points left over from rains earlier in the week are creating the dangerous heat.

Heat is the number one weather killer.  Heat exhaustion and heat stroke can set in within minutes.  The hot weather is most dangerous to children and elderly adults.
