* From late tonight through late Wednesday night.
* Widespread heavy rain of 1 to 3 inches with localized amounts
possibly exceeding 5 inches from the remnants of Tropical Storm
* Rapid runoff from the heavy rain will lead to poor drainage
flooding and fast rises on area streams and creeks. River flooding
is not expected at this time. However, the development of larger
areas of heavy rain could focus significant runoff into one or
more larger river basins, increasing the threat for river flooding.
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
