Logan County spared worst in Friday evening storm

[May 16, 2009]  Tornadoes were a great concern, and cloud rotation was evidenced by radar and viewed by weather spotters. But it was the heavy rains that caused the greatest hazard in Logan County last evening. The pounding rains reduced visibilities and caused flash flooding as it fell over already saturated ground and ran off into swollen creeks.

Even though there were heavy rains, some areas of high winds and lightning, the county was mostly spared damage, and it could have been much worse.

The squall line coming up out of the southwest, stretching several states long, developed strong rotation as it passed over southern Logan County at about 5:45 p.m. It was lucky that it didn't drop down any lower than it did or reach the ground, emergency management director Dan Fulscher said this morning.

"There were over 11 miles of rotation over southern Logan County," Fulscher said. The systems that cause the worst storms are the ones that track northeast like this one did last night, he said. Hooks are a serious rotation condition. Hooks are created when there is an abrupt change in the wind direction. As the system tracked over southern Logan County, the movement changed from northeast to east in several places, creating a number of hooks.

Latham had the highest reported winds clocked, at over 60 mph. Other parts of the county had 30 to 35 mph winds.

Hit hardest were Cornland and Latham in the southeast part of the county. In Latham the old high school, which is now an apartment building, had 1 1/2 feet of water. The lower apartments were evacuated, and the Red Cross is there assisting residents.

Between 3 and 3.3 inches of rain was reported in various areas of the county, with extreme south and north most affected.

Illinois Route 121 had water flowing over it in various areas. A number of county roads and city streets flooded. Street workers and officers slogged through floodwaters to remove debris that was clogging drains of main streets. Kickapoo Creek was flooding Lawndale.

The National Weather Service is monitoring creek levels. Kickapoo Creek is rising from 7 feet and expected to crest in flood stage at 14 feet. Salt Creek is rising from 14.2 feet and is expected to crest at 21 feet. Between 22 and 22.4 feet is when Lincoln Lakes would need to be evacuated. Fulscher said that they would be keeping a close eye out there.

There were several widespread areas of power outages throughout the evening. They included Elkhart, Cornland, Beason, Mount Pulaski, Beason, north of Lincoln and a few sporadic locations in Lincoln. No power was reported to be out yet this morning.

Fulscher said that a number of county's secondary roads are flooded now, and more could flood later as creeks continue to rise. He recommends that drivers be extra cautious, especially after dark.

No rain is forecast for the next few days. Today is expected to reach 65 degrees, becoming sunny and breezy, with 17 to 21 mph winds out of the northwest and gusts up to 30 mph.
