The Iowa Department of Transportation (DOT) is advising central and west central Iowa motorists that sustained wind speeds of 30 to 40 mph and gusts between 50 to 60 mph, are expected across Iowa this afternoon. The rest of the state is expected to experience sustained winds of 25 to 35 mph with gust of up to 50 mph. Drivers on Iowa roadways should be alert to the effects of these winds on high-profile vehicles and vehicles towing trailers.
The National Weather Service has issued a high wind warning effective until 6 p.m. today for 25 counties in central west central Iowa. A wind advisory is in effect across the remainder of the state. Strong southwesterly winds will continue to strengthen this morning and become westerly during the day. Strong winds are capable of snapping power lines, toppling road signs and blowing debris onto the roadway. Never cross a roadway where downed power lines, poles or transformers are present. Do not try to free lines or remove debris yourself. Call 911 if you observe such items on the roadway so emergency assistance can be provided.

The changing of the seasons means Iowans need to be prepared for severe weather. Cass County Emergency Management Coordinator Mike Kennon says Severe Weather Awareness Week in Iowa is April 2nd through the 6th. Leading up to that statewide event are several Severe Storm Spotter training classes, one of which is being held at the Lewis Fire Station March 14th, beginning at 7-p.m. Kennon says anyone interested in becoming a trained Weather Service spotter is welcome to attend, free of charge.
The main event during Severe Weather Awareness Week, is the Statewide Tornado Drill, on Wednesday, April 4th, beginning at around 10:15-a.m. Kennon says the courthouse will participate in the drill. He says the Cass County Communications Center will be notified, and announce the drill within the courthouse. They’ll also activate tornado sirens in Atlantic. Businesses, schools and all communities in the County are encouraged to participate in the drill, as though an actual tornado were spotted and threatening public safety.
Kennon says the state and National Weather Service might need to look at pushing future Severe Weather Awareness activities week into March, as recent severe weather events across Iowa and the nation, such as the tornados in Branson, Missouri have shown they can occur anytime, but are happening with more and more frequency in March, instead of April and May.

Can you tell the difference between a “scud” cloud, and a “wall” cloud? Do you know the difference between a “funnel cloud,” and a Tornado? Trained storm spotters know the difference, and serve as the local eyes for the National Weather Service when severe weather threatens. Each year, meteorologists with the National Weather Service (NWS) travel to most of the 51 counties they serve to provide a comprehensive multi-media spotter training presentation. The classes are hosted by local emergency management officials, fire departments and a few amateur radio clubs. There are several opportunities for you to attend one of these classes free of charge. The classes typically last one-to two-hours.
The courses cover information about severe weather climatology, severe thunderstorm types, different weather threats and how to identify them, how to report severe weather, spotter safety and severe weather communications. If a class is not offered in your county, you are welcome to attend a class in a nearby county.
In the KJAN listening area, classes are being offered in March at the following locations and times….
March 8th at the Prescott Fire Station in Adams County, beginning at 7-p.m.
