* Through this evening
* heavy rain is expected to come in waves of thunderstorms
overnight and during the day on Thursday. Rainfall amounts in
excess of 3 inches with locally higher amounts are possible.
* Heavy rainfall will result in flooding of low lying or poor
drainage areas... and ultimately dangerous flash flooding on
smaller creeks and streams. Significant rises on larger
streams and rivers will also be possible.
A Flash Flood Watch means that flash flooding is possible but not
imminent in the watch area. People in the watch area should be
aware of the possibility of heavy rainfall and flash flooding.
Check your preparedness requirements... especially if you live in
flood prone areas. Stay informed... and be ready for quick action
if flooding is observed or if a Flash Flood Warning is issued.
