There are thunderstorms forming west of the County. Some of these storms have been prolific hail producers with continuous cloud to ground lightning being reported. Severe warnings likely this afternoon.
The National Weather Service has issued a FLASH FLOOD WATCH for Montgomery County until 11:00 PM EST. At 1:59 PM, Doppler radar indicated a line of storms approaching the county that will be capable of producing flash flooding.
This mornings storms initiated several rescues of stranded motorist in the DC metro area after vehicles were driven through areas of flooding. Guidance indicates a little over an inch of rainfall could start flooding in the DC metro area.
Residents should expect extremely heavy rain that will flood low lying areas, and streets with slow drainage. Do not cross flooded roads. Flooded areas may be harder to identify at night. Use caution while driving.
A SEVERE THUNDERSTORM WATCH means conditions are favorable for severe storms in and close to the watch area. Severe thunderstorms can and occasionally do produce tornadoes with little or no advanced warning. Residents should be on the lookout for threatening weather conditions and listen for later statements and possible warnings.
In the event of a Severe Thunderstorm Warning:
Go to a safe place, such as a building or car.
If no structure is available, find an open space and squat low to the ground as quickly as possible.
Avoid tall structures such as towers, tall trees, telephone lines or power lines.
Stay away from natural lightning rods made of metal such as golf clubs, fishing rods, bicycles or metal fences.
Stay away from bodies of water and flood-prone areas.
Avoid bathtubs, water faucets and sinks because metal pipes can transmit electricity.
Turn on a battery-operated radio or television.
Don't use a cell phone or land line phone.
Don’t use a computer, if possible.
The safest place to be during a tornado is in a basement. Fit under a work bench or other piece of sturdy furniture. If no basement is available, seek shelter on the lowest floor in a hallway or closet. Use blankets or pillows to cover your body and always stay away from windows.
Evacuate mobile homes and vehicles immediately. Do not use highway overpasses as shelters. If no shelter is available, lie flat in the nearest ditch or other low spot and cover your head with your hands.
Do not wait to hear or see this tornado before you take action. Tornadoes that form at night and those that are rain wrapped may not be visible.
