INSTRUCTION: A Coastal Flood Warning means that moderate or major tidal flooding is occurring or imminent. Be prepared for rising water levels and take appropriate action to protect life and property. Follow the recommendations of local emergency management officials. Do not drive your vehicle through flood waters. The water may be deeper than you think it is. You will be putting yourself in danger and your vehicle may be damaged, leading to costly repairs. Visit the Advanced Hydrologic Prediction Service at water.weather.gov/ahps for additional water level and flood impact information for your local tide gauge. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Always obey posted Beach Flags. If you enter the surf zone, always have a floatation device with you and swim near a lifeguard if possible. If caught in a rip current, relax and float and do not swim against the current. If able, swim parallel to the shoreline. If unable to escape, face the shore and call or wave for help.

The final form taken by a growing cumulus cloud is the
cumulonimbus cloud, which is very tall and dense.
The tower of a cumulonimbus cloud can soar 23 km into the atmosphere, although
most commonly they stop growing at an altitude of 6 km.
Even small cumulonimbus clouds appear very large in comparison to other cloud types.
They can signal the approach of stormy weather, such as thunderstorms or blizzards.

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.
