La Soufriere volcano, St. Vincent:

La Soufriere volcano remains in a continually active state, and additional eruptions of ash plumes are possible at any time. The most recent report from the Satellite Analysis Branch and UWI Seismic Research Center (SRC), indicate that the latest eruption occurred on Sunday afternoon and a plume of ash spread southward and Southwestward over the eastern Caribbean from 13N to 14N between 61W and 63W. Numerical models forecast little change in wind direction through the next twelve hours.

Saharan Dust:

Observations of Saharan Dust show that there is a significant reduction in the presence of dust particles across the Eastern Caribbean. The latest model guidance of Surface Dust Concentration indicate that the concentration will remain minimal within the next two days.

Volcanic Ash:

The Volcano remains in a very active state, and additional eruption and ash plumes are possible at any time without warning.

Upper-level winds near St. Vincent are moving towards the southeast, so there is a low potential for some ash to reach the State of Grenada in the event of another eruption within the next 12 hours.

The Meteorological Office continues to closely monitor satellite imagery and analyze forecast winds to determine the likelihood of ash intrusion into Grenada. Nonetheless, the following warnings have been issued, valid for today and tonight.

Warnings:     

1. Low potential for ashfall.
2. Persons with respiratory illnesses should continue to exercise the necessary precautions.
3. Mariners transiting the nearby waters are urged to exercise caution since remnant volcanic ash or floating volcanic debris may be encountered.

Next advisory: 8:00 pm, Monday, April 19^th
