The same weather pattern that brought heavy rain to the District Saturday, resulting in 1.64 inches at Reagan National Airport, the wettest day since December 7, 2011, produced slow-moving flooding downpours in the District again tonight resulting in flash flooding.
A shower first blossomed over the Northwest part of the city just after 7 p.m. then grew in intensity, producing rain rates of 2 to 3 inches per hour.
Parts of Rhode Island Avenue, Florida Avenue and 1st and 2nd Streets were under water while the downpours flooded parts of the Metro.

Just before the rain ended, totals were up to 3 inches in Northwest. Here are other top rainfall totals from WeatherBug Stations.
Even though the rain is subsiding, runoff will continue as will the flood hazards. Keep in mind it only takes 6 inches of running water to stall out a vehicle and cause you to lose control on the roadway. A foot of water will float a car away. It’s even more difficult to spot flooded roadways at night, so drive with extra caution.
These showers are quite intense but far and few between and compact in size that you may not know a roadway is covered in water until you approach it. Additional showers and storms will redevelop through early next week as Isaac's remnant low slowly moves closer. This will keep the flash flooding threat high.
Stay with ABC7 and WTOP for the latest on the ongoing flash flooding potential.
