| 释义 |
A Coastal Flood Watch is issued by the National Weather Service of the United States when coastal flooding along the coast of the Atlantic Ocean, Pacific Ocean, or the Gulf of Mexico is possible. The flooding must be due to water being forced from the nearby body of water onto land, and not from rainfall. Nor'easters, hurricanes, tropical storms, and thunderstorms can all lead to the issuance of a Coastal Flood Watch.[1] ExampleThe following is an example of a Coastal Flood Watch issued by the National Weather Service office in Taunton, Massachusetts.[2] 000WHUS41 KBOX 062129CFWBOXURGENT - IMMEDIATE BROADCAST REQUESTEDCOASTAL HAZARD MESSAGENATIONAL WEATHER SERVICE TAUNTON MA429 PM EST WED FEB 6 2013...COASTAL FLOOD WATCH FOR THE MASSACHUSETTS EAST FACING COASTLINEAROUND THE TIME OF THE FRIDAY EVENING AND SATURDAY MORNING HIGHTIDES....A POWERFUL COASTAL STORM MAY PRODUCE MODERATE COASTAL FLOODINGFRIDAY EVENING AND MODERATE TO MAJOR COASTAL FLOODING SATURDAYMORNING ALONG WITH POTENTIALLY SEVERE EROSION.
