| - | Message 1's have been extended until 2:00 AM Wednesday as the threat for heavy rainfall will continue into the overnight period. |
| - | A boundary is approaching the District from the E and will increase moisture further from already elevated levels. This boundary may initiate new thunderstorm development this evening. Due to the abundant moisture available thunderstorms will be very capable of producing heavy rainfall. |
| - | Even weak to moderate thunderstorms will be capable of producing brief heavy rainfall. Stronger storms will have the potential to produce excessive runoff that may lead flash flooding. Some areas of the District today have already reached or exceeded 0.5-1.0" of rain and it may not take as much rain from subsequent storms to produce excessive runoff. |
WORST CASE SCENARIO: A slower moving thunderstorm or briefly anchored thunderstorm may result in up to 2.0" of heavy rainfall in 45-60 minutes.
