Flood Watch / Flood Statement
Expires 8:00 AM CDT on June 23, 2003

The National Weather Service in Omaha has issued a Flood Watch for the following counties in southeast Nebraska... Butler... Cass... Seward... Lancaster... Otoe... Saline... Nemaha... gage... Johnson... Jefferson... Richardson and Pawnee... and also Fremont County in far southwest Iowa. The Flood Watch is in effect until 600 am CDT Monday morning.
Thunderstorms are likely to develop over southeast Nebraska and far southwest Iowa late this afternoon or tonight. There is a chance that these storms will produce excessive rain resulting in flooding or flash flooding. The ground is moist from recent heavy rainfall. A combination of high humidity and a slow moving front approaching the area means that conditions are favorable for more heavy rain to develop tonight.
A Flood Watch means that flooding of small streams... creeks and other drainage areas is possible in the watch area. If you are in the watch area... keep an eye on the weather and be prepared to take immediate action if flooding develops. If a Flash Flood Warning is issued... do not stay in areas that may flood. Move to higher ground.
