Widespread areas of dune erosion with localized overwashes are expected during the Thu evening and Fri morning high tides.
INSTRUCTION: Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. If you enter the surf zone, always have a flotation device with you and swim near a lifeguard. If caught in a rip current, relax and float, and do not swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and yell or wave for help.

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.
