TIME/DATE: Wednesday, April 14, 2021 (8:00 PM)
La Soufriere volcano, St. Vincent: The volcano continues with its episodic pattern of eruptions from its summit. Its latest eruption occurred this evening, and the ash plume is forecast to reach Barbados tonight. Ash may be reaching the surface of the ocean, and low-level visibility may be reduced. Explosions and accompanying ashfall of similar magnitude are likely to continue to occur over the next few days.
Saharan Dust: Model guidance of Surface Dust Concentration indicates that there will be varying intensities in the concentration of dust/haze throughout the next 48 hours.
Volcanic Ash: Remnant volcanic ash from earlier explosions is observed on satellite imagery. This volcanic ash is moving towards Barbados and over the tropical Atlantic Ocean. However, there is a low possibility of ash being brought back to the Lesser Antilles as it descends through atmosphere and is pushed along by the low-level easterly winds.
The Met Office continues to 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 tonight.
Warnings:
(1) Low potential for ashfall; however, moderate haze may reduce visibility.

(2) Persons with respiratory illnesses should continue to practise the necessary precautions.
(3) Mariners venturing off to the east of the islands are urged to exercise caution as volcanic ash or floating volcanic debris may be encountered.
