SAC-CRAWFORD-CARROLL-AUDUBON COUNTIES…

…HEAVY RAIN AND ISOLATED THUNDERSTORMS…

A BAND OF MODERATE TO HEAVY RAIN WITH ISOLATED THUNDERSTORMS CONTINUES TO TRACK NEARLY DUE NORTH ACROSS WESTERN IOWA THIS EVENING. BRIEF HEAVY DOWNPOURS WITH BETWEEN A HALF TO ONE INCH OF RAIN MAY FALL OVER THE NEXT FEW HOURS.

THE RAIN MAY BRIEFLY REDUCE VISIBILITY AND CAUSE ROADWAYS TO BE SLICK WITH PONDING WATER. IF YOU ARE TRAVELING ACROSS THE REGION THOUGH LATE THIS EVENING EXERCISE SOME CAUTION TO REACH YOUR DESTINATION SAFELY.

PONDING OF WATER WILL BE COMMON IN URBAN AREAS WHERE RUNOFF MAY BE HINDERED BY POOR DRAINAGE. TRAVELING AT HIGHWAY SPEEDS MAY RESULT IN REDUCED TRACTION DUE TO HYDROPLANING. IF NECESSARY SLOW DOWN.
