Advisory
Flash Flood Watch
Flash Flood Watch 
Flash Flood Watch in effect from 2 AM Monday until Monday Afternoon. Be prepared to take action in the event that flooding develops.
* A line of strong thunderstorms is expected to move through the
area late tonight and Monday morning. Widespread rainfall totals
of one to three inches are forecast, with locally higher amounts
possible with the strongest storms. The storms will likely move
out of the area by Monday afternoon.
* The areas of greatest risk are poor-drainage and urban locations
where rapid runoff may cause localized flash flooding. Quickly
responding small streams may also experience flooding in areas
receiving the heaviest rainfall. The storms are expected to move
through the area just before or during the morning commute.
Motorists should be prepared for torrential downpours and
potential flooding as the storms move through.
Precautionary/preparedness actions...
A Flash Flood Watch means that there is the potential for flash
flooding which can be life-threatening. Heavy rain is expected to
occur over a short period of time. Rapidly rising flood waters
may quickly inundate roadways and areas of poor drainage. Streams
and creeks could leave their banks, flooding nearby properties.
Please monitor the forecast, especially if you live in a location
that is prone to flooding. Be prepared to take action if a Flash
Flood Warning is issued for your area.
