Weather Alert in South Carolina
Flash Flood Warning issued August 22 at 6:47PM EDT until August 22 at 8:15PM EDT by NWS Charleston SC
AREAS AFFECTED: Berkeley, SC; Charleston, SC; Dorchester, SC
DESCRIPTION: At 647 PM EDT, emergency management officials reported flash flooding is still ongoing across much of the Charleston Metro Area. Many roads are reported closed and flooded across Downtown Charleston, North Charleston and surrounding communities. Radar shows bands of moderate to locally heavy rain expanding across the Metro area again. This will worsen ongoing flash flooding, especially as an elevated high tide approaches. As much as 3 to 6 inches have fallen so far today. An additional inch could fall. Tides in the Charleston Harbor are expected to reach between 7.7 and 7.9 ft MLLW, which is well into the moderate flood range. With drainage systems full of saltwater, any heavy rainfall that falls will immediately result in additional flooding. In addition, people along Church Creek in West Ashley should carefully monitor water levels this evening. Flooding could develop in neighborhoods near the creek, including areas along Winners Circle. HAZARD...Life threatening flash flooding. Thunderstorms producing flash flooding. SOURCE...Emergency management reported. IMPACT...Life threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses. Some locations that will experience flash flooding include...

Next Topic: Evaporation
Drizzle is precipitation in the form of water droplets which are
smaller than raindrops.
Drizzle is characterized by fine, gently falling droplets and typically does not
impact human habitation in a negative way. The exception to this is freezing drizzle,
a condition where drizzle freezes immediately upon reaching earth's surface.
Freezing drizzle is still less dangerous than freezing rain, but can
potentially result in hazardous road conditions.

Next Topic: Fractus Clouds
Fog is technically a type of stratus cloud, which lies along the
ground and obscures visibility.
It is usually created when humidity in the air condenses into tiny water droplets.
Because of this, some places are more prone to foggy weather, such as regions
close to a body of water.
Fog is similar to mist; both are the appearance of water droplets suspended in
the air, but fog is the term applied to the condition when visibility is less than 1 km.
