Flood warning for E Montgomery and W Howard Co

By Jason Samenow

* Full Forecast | Hefty rain totals likely | Tornado risk | Dr. Gridlock *

Updated at 2:55, and 2:20 p.m. Originally posted at 1:30 p.m.

The Flash Flood Warning issued around 1:20 p.m. continues for eastern Montgomery and western Howard county through 4:15 p.m. The warning has been extended northward into eastern Carroll and western Baltimore counties.

The National Weather Service has also issued a Flash Flood Watch, covering the entire region, and cautions:

RAINFALL AMOUNTS BETWEEN 2 AND 4 INCHES ARE EXPECTED ACROSS MOST LOCATIONS WITH ISOLATED AMOUNTS UP TO 5 INCHES IN BANDS OF HEAVIER RAIN AND THUNDERSTORMS.

While rain is more scattered than earlier, intermittent showers - some heavy - will continue to pulse through the region (including those not under warnings) from south to north potentially making for a challenging evening commute.

Doppler estimated rainfall suggests 1-2.5" of rain has already fallen in some areas -- particularly those currently under flood warnings. Do not attempt to drive across flooded roadways. Turn around, don't drown.

Monitor severe warnings issued by the National Weather Service and radar on our Severe Weather Tracking Station below. Also, comment below with conditions where you are. And see our full forecast through next weekend.

HappyArmyWife, you are probably right. Take it slowly, allow for more time, and remember to never attempt crossing a flooded roadway.

We got over 3 inches here in Brookeville, MD, right where this warning was issued. On-and-off heavy rain all morning, through 4PM.
