... Flash Flood Watch in effect from late tonight through Sunday
morning...
The National Weather Service in Des Moines has issued a
* Flash Flood Watch for portions of central Iowa... north central
Iowa... northwest Iowa... south central Iowa... southeast Iowa...
southwest Iowa and west central Iowa... including the following
areas... in central Iowa... Boone... Dallas... Hamilton... Hardin...
Jasper... Marshall... Polk... Poweshiek... story... Tama and
Webster. In north central Iowa... Humboldt... Kossuth and
Wright. In northwest Iowa... Emmet... Palo Alto and Pocahontas.
In south central Iowa... Appanoose... Clarke... Decatur... Lucas...
Madison... Mahaska... Marion... Monroe... Ringgold... Union...
Warren and Wayne. In southeast Iowa... Davis and Wapello. In
southwest Iowa... Adair... Adams... Cass and Taylor. In west
central Iowa... Audubon... Calhoun... Carroll... Crawford...
Greene... Guthrie and SAC.
* From late tonight through Sunday morning
* thunderstorms are expected late Saturday night into Sunday
morning with the potential for heavy rainfall. Many areas from
northwest into central and southern Iowa are primed for flooding
problems with precipitation amounts anywhere from two to ten
inches in the past seven days. Many locations may see additional
one to two inch rains... with local amounts from two to four
inches quite possible. Rains of this magnitude could quickly
develop flash flooding considering our current moist soil
conditions.
* Flash flooding may develop with rapid rises in smaller streams
and creeks. Rural roads may washout or become inundated with
standing water making them impassable. Significant urban
flooding could result as well with ponding water and possibly
water in basements... especially if sump pumps fail.
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation. You
should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
