* TEMPERATURE…Highs will range from the middle 80s to lower 90s. Peak heat index values in the middle 90s–approaching 100 at times–can be expected this afternoon.

* IMPACTS…Prolonged exposure to heat and humidity may lead to heat-related illness if precautions are not taken. People planning outdoor activities–and people attending or participating in athletic and other outdoor events–today should be cognizant of these unusually warm and humid
conditions.

Heat Advisory for Iowa Counties in orange until 7-p.m.

PRECAUTIONARY/PREPAREDNESS ACTIONS

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.

Take extra precautions, if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9 1 1.

Dry SE Iowa gets up to 7″ rain, prompting flash flooding

September 21st, 2017 by Ric Hanson

In a region of the state that’s been plagued by extremely dry weather much of the summer, some roads were closed this (Thursday) morning due to flash flooding, the result of multiple downpours overnight. Meteorologist Craig Cogil, at the National Weather Service, says parts of southeast Iowa were drenched, prompting flash flood warnings in Jefferson, Keokuk, Wapello and Washington counties. “We saw persistent thunderstorms in and around the Ottumwa area during the overnight time frame and saw several inches of rainfall,” Cogil says. “We had a few reports of people with personal rain gauges with around seven inches and even a little bit more, just to the south of Ottumwa.”

Some areas of southeast and south-central Iowa had storm after storm roll through during the night, dumping more rain in a few hours than some communities have seen in more than a month. Cogil says, “We did have a report or two of some deeper standing water, but overall, impacts have been somewhat limited just due to how dry it’s been prior to the heavy rainfall.” Several counties across the region were rated in recent days as being under moderate-to-extreme drought conditions, which ended up being a benefit in this storm system. “It’s been so dry, in fact, Ottumwa had one of the largest deficits in the state before this event as far as rainfall is concerned this summer,” Cogil says. “A lot of the soil had the capacity to soak in a lot of the rain that fell overnight and the impacts aren’t as bad as what they normally would have been for such a rainfall.”

The forecast says a wide section of Iowa may see more scattered thunderstorms throughout the day, the last full day of summer. The autumnal equinox is tomorrow at 3:02 PM.
