Recent Locations: Gum Spring, VA   Hamilton, TX   Rock Hill, SC  

Flood Warning issued September 7 at 6:32PM EDT until September 7 at 10:00PM EDT by NWS Charleston SC

AREAS AFFECTED: Charleston, SC

DESCRIPTION: * WHAT...Flooding caused by excessive rainfall is expected. * WHERE...A portion of southeast South Carolina, including the following county, Charleston. * WHEN...Until 1000 PM EDT. * IMPACTS...Numerous roads remain closed due to flooding. Expect many areas of slow moving or standing water. It will take several hours for all the water from these storms to work through local drainage systems in urban areas. * ADDITIONAL DETAILS... - At 625 PM EDT, emergency management officials continued to report road closures across much of the Downtown Charleston area from earlier flooding rains. Drainage of flood waters will become increasingly hampered as high tide approaches in the Charleston Harbor, which will occur shortly after 830 PM. Tide levels are expected to peak in the 7.0 to 7.2 ft mean lower low water range which, in itself, would typically produce salt water flooding in parts of Downtown Charleston. The combination of ongoing fresh water flooding and increasing saltwater flooding will likely produce additional road closures and other impacts across the Downtown area. - Some locations that will experience flooding include... Downtown Charleston, Marion Square, Medical University Of South Carolina, Columbus Street Terminal and The Citadel. - This includes I-26 near mile marker 221.

INSTRUCTION: Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be especially cautious at night when it is harder to recognize the dangers of flooding.

Stratus Clouds Next Topic: Wall Clouds

Stratus clouds are similar to altostratus clouds, but form at a lower altitude and are identified by their fog-like appearance, lacking the distinguishing features of most clouds.

Stratus clouds are wider than most clouds, and their base has a smooth, uniform look which is lighter in color than a nimbostratus cloud. The presence of a stratus cloud indicates the possibility of minor precipitation, such as drizzle, but heavier precipitation does not typically arrive in the form of a stratus cloud.

Altocumulus Clouds Next Topic: Altostratus Clouds

Similar to cirrocumulus clouds, altocumulus clouds are characterized by cloud patches. They are distinguished by larger cloudlets than cirrocumulus clouds but are still smaller than stratocumulus clouds.

Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km) and may resemble, at times, the shape of a flying saucer. These uncommon formations, called altocumulus lenticularis, are created by uplift in the atmosphere and are most often seen in close proximity to mountains.
