Practice Caution
While inclement weather is upon the islands now and expected to continue through this evening, the community is reminded to take the following precautions:

Turn Around, Don’t Drown. Immediately move to higher ground if flash flooding occurs. Water levels can rise rapidly and sweep people away. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away
Stay away from storm drains, culverts, creeks, and streams.
If floodwaters rise around your car but the water is not moving, abandon the car and move to higher ground. If the water is moving, do not leave the car.
Do not camp, park, or hike along streams, rivers, and creeks. These areas can flood quickly and with little warning.
If travel is necessary, practice caution while in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.

X Flooding is a temporary overflowing of water onto land that is normally dry. Flooding may happen with only a few inches of water, or it may cover a house to the rooftop. There are many possible causes of floods including heavy rain, coastal storms and storm surge, waterway overflow from being blocked with debris, or overflow of levees, dams, or waste water systems. Flooding can occur slowly over many days or happen very quickly with little or no warning, called flash floods.
