Met Office Warns Of Approaching Frontal Trough

PR – Forecasters at the Meteorological Office at the Maurice Bishop International Airport  are monitoring a southward tilting Atlantic cold front which entered the Caribbean  Basin located between 15N/16N near Guadeloupe and Dominica, extending between  60W and 72W.  

Northerly to North Easterly winds have been advecting (carrying) cool to chilly air  currents from the cold front across the island chain including the State of Grenada. A  prefrontal trough system is located southeast of the cold front near 55W, about 393 nautical miles (728 km) east of Grenada. 

Weather models suggest that the prefrontal trough will progress northwestward across  the island chain between Tuesday and Wednesday, triggering a northward surge in  moisture and instability from South America to Trinidad and Tobago and the  Windward Islands. This will support increased cloudiness and showery activity which  may be accompanied by isolated thunderstorms on Tuesday and Wednesday  morning. 

Weather conditions on Monday night, are forecast to be generally fair @ first and  chilly, increasing in cloudiness by early morning with the chance of brief, light to  moderate showers.  

On Tuesday, partly cloudy to cloudy skies with light to moderate showers and the  chance of thunderstorms can be expected. Similar conditions are projected for  Wednesday should environmental conditions remain conducive.  

Potential Impacts of the weather conditions are: 

– Low chance of street flooding and/or flash flooding in vulnerable areas on  Tuesday and Wednesday morning 

– Low chance of landslides and rock fall on Tuesday and Wednesday morning

– Territorial coastal waters are projected to be agitated with waves extending to  8 feet in above normal North Easterly swells. 

High surf and marine advisories remain in effect 

NaDMA therefore encourages citizens to be vigilant and monitor weather conditions  closely to ensure safety. 

NaDMA will provide updates on this situation as necessary.
