(Des Moines) Air-conditioners will be on high speed today. A heat advisory is in effect for all of Iowa from 1:00 p.m. this afternoon to 8:00 p.m. this evening.
The National Weather Service says dangerous heat indices of 105 to 110 will be combined with dew points of around 70-degrees. Brenda Brock with the National Weather Service in Des Moines says the temperature could surpass 100-degrees today.
“In southwest Iowa you could have a high today of near 103, our heat index values in Southwest Iowa will be as high as 111 and it will also be windy, that southwest wind will be 15 to 20 miles per hour will gusts to 30,” explained Brock.
If that is the case Atlantic would tie a record that has been around since the mid-thirties.
“Around the Atlantic area the record high is 103 that was set in 1934,” said Brock. “In Central Iowa we have the heat advisory as well and Des Moines may reach a record today. The last time we reached 100 degrees was in 2006.”
Brock says the combination of heat and humidity will create and increased risk of heat exhaustion or other heat related illnesses.
“The main thing we want to get out to folks is dangerous heat indices this afternoon into early this evening; for children, for animals, for people in general, for livestock, because these temperatures, climbing to around 100 degrees-plus, are combined with dew points of around 70 degrees, the impacts can be great from heat exhaustion or other heat related illnesses,” said Brock.
The risk will increase with prolonged outdoor activity with the elderly and very young being most at risk.
A "Heat Advisory" means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.
