In an update to their previous report, the National Weather Service in Des Moines says the hottest weather of the year thus far will impact Iowa through the upcoming weekend. High temperatures will top out in the upper 80s to mid-90s each day, with overnight lows only in the 70s each night. Heat index values will approach 100°F each afternoon/evening, making this easily the hottest stretch of weather experienced since last summer. The hottest temps are likely in the western half of Iowa. A Heat Advisory is in effect for three counties in Northwest Iowa.

The latest information puts the Heat Index (how it feels) in Atlantic, Council Bluffs and Sheldon at around 103 degrees, Sioux City 105, 101 in Carroll, Des Moines and Ft. Dodge, 102 in Algona and Ames, and 100 in Estherville. Other locations will have a heat index of 95-to 97-degrees. If planning outdoor activities, avoid prolonged exposure to the heat and be HEAT SMART.

Heat is the #1 weather-related killer in the United States! Here are a few tips on staying safe during episodes of dangerously hot weather:

• First and foremost, minimize your time outside, especially during the hottest parts of the day. Stay in an air conditioned building.
• If you must be outside, wear light-colored and loose-fitting clothing.
• Drink plenty of water or natural juices if you are out in the heat, even if you do not fell thirsty. Avoid alcoholic or caffeinated beverages.
• Think about others! NEVER leave children in a car on even a moderately warm day as conditions in the car can quickly heat to unhealthy levels. Check on the elderly or other people at risk.
