AMES, Iowa – Jan. 27, 2013 – 9 a.m. update – While the first wave of precipitation continues to move northeast through the state, a second wave has entered Iowa from the south. Although not as intense and wide as the first band, more moisture is still moving northward through the Midwestern region.
Air and pavement temperatures are remaining fairly steady or rising slightly. Temperatures in the southwest corner of the state and along a line that stretches up the I-29 corridor to Sioux City is above freezing; most of the rest of the state is at or below freezing.
Instant icing of windshields and roadway surfaces (as well as driveways, sidewalks and parking lots) can be expected in the areas with freezing temperatures.
Several crashes have been reported this morning. Bridges, as well exit and entrance ramps, freeze first and stay slick longer since they are elevated. Drivers need to exercise additional caution in these areas. Road maintenance crews are also directing additional attention to these problem areas.
If possible, postpone travel in ice-covered areas of the state. If you must travel, reduce your speed, wear your seatbelt and put extra space between your vehicle and the others sharing the roadway.
Attention regional travelers: Check with your airport regarding potential travel delays and cancellations. Freezing rain is also occurring in parts of Minnesota and Wisconsin; heavy snow is forecast for some of the northern regions of these states, as well as Michigan.
