TROPICAL STORM BRET BECOMES EARLIEST NAMED STORM SO FAR SOUTH IN THE ATLANTIC – MONTSERRAT CAN EXPECT SHOWERS AND GUSTY THUNDERSTORMS THROUGH TUESDAY

An unusually strong system for June will pass through the southern part of the Windward Islands with tropical storm conditions through Tuesday.

The system strengthened into Tropical Storm Bret on Monday afternoon. Since Bret formed prior to June 22, it has become the earliest named storm to form in this part of the Atlantic since official records were kept in 1851.

Because of the compact nature of the storm, adverse conditions are likely to hug the coast of Venezuela, while moving on a westward path through the southern part of the Windward Islands and a portion of the Leeward Antilles.

People on the islands from Trinidad and Tobago to Grenada, St. Vincent and the Grenadines, Barbados, St. Lucia, Margarita and Tortuga can expect showers and gusty thunderstorms through Tuesday.

Bathers and boaters should heed all advisories as seas and surf will be dangerous.

Rain is generally needed on these islands since they receive little rain on an annual basis. However, too much rain can fall too fast and lead to flash flooding and mudslides. Rainfall will average 2-4 inches with locally higher amounts possible.

MONTSERRAT VOLCANO OBSERVATORY (MVO) WEEKLY REPORT FOR THE PERIOD JUNE 9 TO 16TH, 2017

Activity at the Soufrière Hills Volcano remains low.

The seismic network recorded three volcano-tectonic earthquakes this week.

Measurements of the SO2 flux were made using the helicopter on 13 June. A total of nine traverses beneath the plume were carried out, with an average SO2 flux of 161 tonnes per day.
Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham Valley can be destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.

The Hazard Level is 1. There is no public access to Zone V, including Plymouth. Maritime Zones E and W are daytime transit only between sunrise and sunset (boats may sail through the zone but must not stop). Anyone who ignores these restrictions is liable to be prosecuted. Continue reading

TWO DISTURBANCES ALREADY IN THE ATLANTIC BASIC FOR JUNE

On this Friday morning, the National Hurricane Centre (NHC) is monitoring two areas over the Atlantic basin. One is a tropical wave located over the far eastern Atlantic Ocean several hundred miles southwest of the Cabo Verde Islands. The associated cloudiness and showers have become better organized since yesterday, and additional slow development is possible during the next few days while the wave moves westward at 15-20 mph over the tropical Atlantic.

The second area is the northwestern Caribbean Sea and the Yucatan peninsula, where a broad area of low pressure is expected to form during the next day or two. Conditions appear to be favourable for the gradual development of this system while it moves slowly northwestward into the southern Gulf of Mexico early next week.
