Flood Watch


The National Weather Service in Sterling Virginia has issued a

* Flood Watch 
* From this evening through Sunday evening.

* A slow moving front will lead to multiple rounds of moderate/
  heavy rainfall from this evening through Sunday evening.
  Widespread rainfall amounts of 1 to 2 inches are likely, with
  localized amounts over 2.5 inches possible.

* Heavy rain may lead to flooding of streams and some rivers. 
High water may also develop in low-lying and poor drainage areas

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should
be prepared to take action should flooding develop.
This type of rainfall could lead to Flash Floods.  Flash floods occur within a few minutes or hours of excessive rainfall or a dam failure. Flooding is a longer-term event and may last a week or more.

Most flash flooding is caused by (1) slow-moving thunderstorms, (2) thunder-storms repeatedly moving over the same area or (3) heavy rains from hurricanes and tropical storms.

Flash floods can roll boulders, tear out trees, and destroy buildings and bridges.

Densely populated areas have a high risk for flash floods. The construction of buildings, highways, driveways, and parking lots increases runoff by reducing the amount of rain absorbed by the ground.

Water can erode the roadbed creating unsafe driving conditions.

Many flash floods occur at night when flooded roads are hard to see.

2 feet of water will float your car, truck or SUV!!! 6 inches of fast-moving floodwater can knock you off your feet.

Nearly half of all flash flood fatalities are auto related. If your car stalls, leave it and seek higher ground, if you can do so safely.

Underpasses can fill rapidly with water, while the adjacent roadway remains clear. Driving into a flooded underpass can quickly put you in 5-6 feet of water.

Flood Safety Tips...

Never try to walk, swim, or drive through swift-moving floodwater. Remember, 2 feet of water will float your vehicle and 6 inches of fast moving floodwater can knock you off your feet. 

If you come upon floodwaters, STOP, TURN AROUND AND GO ANOTHER WAY!! 

Do not attempt to drive through a flooded road.
