| - | Message 1's have been issued for the entire District and will be valid until 10:00 PM this evening. |
| - | Widely scattered thunderstorms are expected to develop over the District shortly. Strong thunderstorms will have the potential to produce heavy rainfall which may lead to excessive runoff and possibly flash flooding. Due to the rainfall over the past couple days and a saturated ground in many areas it will not take as much rain as normal to produce excessive runoff. |
| - | One to two rounds of storms are likely into the evening with thunderstorm activity expected to diminish around sunset or shortly after. Storms will typically move from NW to SE at around 20mph. Some storms along surface wind convergence lines may move more slowly. |
WORST CASE SCENARIO: A strong slower moving thunderstorm or training of thunderstorm cells may produce up to 2.5" in 60-90 minutes.
