SPECIAL WEATHER BULLETIN
DATE ISSUED: Thursday, 29 June, 2017 TIME ISSUED: 10:45 AM
A FLOOD ADVISORY IS IN EFFECT FOR ST. MAARTEN
FOR THE NEXT 12 HOURS
A tropical wave is currently passing through the Eastern Caribbean, coupled with favorable upper level conditions over our local area and the accompanying surge of moisture will cause unsettled weather. As a result, cloudy skies, breezy conditions isolated showers, some of which could be heavy, and isolated thunderstorms are expected today.
Due to already saturated soils from persistent rainfall and additional rainfall that is expected today, a flood advisory is now in effect. Therefore, motorists and persons living in low-lying areas should remain vigilant due to possible street flooding and localized flooding.
After the wave exits the region, the Saharan dust and Atlantic high pressure system will reestablish across the local area and limit significant precipitation.
A Special Bulletin is issued for weather events that are unusual, cause general inconvenience or public concern (requiring the attention and action of fire department and police authorities) and cannot adequately be described in a regular weather forecast.
A Precautionary statement means that there is a slight possibility (< 30% chance) of occurrence within the next 8 to 24 hours.
A Heavy Rainfall Watch is an announcement when heavy rainfall is evident within the following hours.
A Heavy Rainfall Advisory is an announcement when heavy rains are about to occur or occurring already, but are not strong enough to require a warning.
A Heavy Rainfall Warning is an announcement when heavy rains are about to occur or are occurring already.
