The National Weather Service in Des Moines has issued a dense fog
advisory... which is in effect until 9 am CST this morning.
* Visibility... widespread visibilities less than one quarter mile.
Expect improved conditions to arrive into central Iowa late
* Impacts... the restricted visibilities will create hazardous
travel conditions. In addition... light freezing drizzle may
accompany the fog over far northern Iowa near the Minnesota
border and may create icy conditions on secondary roads.
A dense fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow down...
use your headlights... and leave plenty of distance ahead of you.
