* Storm total snow accumulations... nine to twelve inches of snow is expected by Saturday.
* Winds... brisk east winds of 15 to 25 mph will be common today into Thursday. By Friday... winds will become northwest at 25 to 35 mph with higher gusts.
* Visibility... visibilities less than a quarter mile during the heaviest snows can be expected. Increasing winds and snow coincident by Friday will reduce visibilities to near blizzard conditions especially west of Interstate 35.
* Impacts... travel will become increasingly difficult in the watch area on on Christmas eve night and Christmas day as snow accumulates and winds increase. In the heaviest snow areas... travel may become nearly impossible due to blowing and drifting snow Thursday night into Friday.
Precautionary/preparedness actions...
A Winter Storm Watch means there is a potential for significant snow... sleet... or ice accumulations that may impact travel. Continue to monitor the latest forecasts.
Areal Flood Watch
Statement as of 9:21 PM CST on December 23, 2009
... Flood Watch remains in effect from 6 am CST Thursday through late Thursday night...
The Flood Watch continues for
* portions of central Iowa... northeast Iowa... south central Iowa and southeast Iowa... including the following areas... in central Iowa... Jasper... Marshall... Polk... Poweshiek and Tama. In northeast Iowa... Black Hawk. In south central Iowa... Appanoose... Clarke... Decatur... Lucas... Mahaska... Marion... Monroe... Warren and Wayne. In southeast Iowa... Davis and Wapello.
* From 6 am CST Thursday through late Thursday night
* moderate to heavy rainfall... and some thunderstorms... are expected. This rainfall... combined with snow melt... may lead to flooding on area rivers. Localized flooding may also occur in other areas... such as urban areas... where the drainage systems may be impaired due to snow and ice clogged intakes.
* Another concern is break up ice jams on area rivers. The runoff will likely be enough to break up the ice especially as one moves southward. Since the river ice is relatively thin... though... only minor... localized problems due to ice jams are expected.
Precautionary/preparedness actions...
A Flood Watch means there is a potential for flooding based on current forecasts.
You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
