(Des Moines) The National Weather Service issued a freeze warning for almost the entire state, including southwest and west central Iowa, from 1:00 a.m. to 9:00 a.m. on Saturday.
Frost and freeze conditions will kill sensitive vegetation and possibly damage unprotected outdoor plumbing.
Sub-freezing temperatures as low as 28 degrees are expected early tomorrow morning.
Forecasters say to take steps to protect tender plants from the cold. To prevent freezing and possible bursting of outdoor water pipes, they should be wrapped, drained, or allowed to drip slowly. Drain in-ground sprinkler systems and cover the above-ground lines to protect them from freezing.
