ANOTHER SWELL EVENT TO IMPACT MONTSERRAT ON WEDNESDAY AFTERNOON

by Shirlian Queeley
A powerful low-pressure system is pushing low period swells of moderate heights across the Atlantic that will reach the northern Caribbean, including Antigua and Barbuda. The swells will start to arrive tonight across the Bahamas, tomorrow morning across Hispaniola and Puerto Rico and Wednesday afternoon across the Leeward Islands, including Antigua and Barbuda. That's according to Dale Destin, Meteorologist/Climatologist for the Antigua and Barbuda Meteorological Service Climate Section.
According to Destin, these swells will come nowhere close to the last one in size and duration. The swell waves will be moderate – 2 to 3 metres across the northeast Caribbean and larger for the islands to the west. However, high surfs will pummel our shorelines with heights of 4.5 metres or 15 feet, getting higher as you go west through the islands. Such high swells and surfs will produce an elevated threat to life and property in the surf zone. The high surfs that will result in beach closures as swimming conditions will become extremely dangerous for beachgoers. The event will likely cause major beach erosion; possibly flooding of low-lying coastal roads; disruptions to marine recreation and businesses; financial losses and damage to coral reefs. Although relatively small, this swell episode may also cause disruptions to potable water from desalination as turbulent seas could increase the turbidity of the water above safe levels for the desalting plants. A high surf warning has been issued by the Met Office for Antigua and the rest of the northeast Caribbean. Other Offices are expected to issue warnings for as far west as the Bahamas and extending south to the northern Windward Islands. Swells could exceed 5 m (17 ft) across the Bahamas. The impact on shorelines will not be the same everywhere. Depending on the depth, size, shape and the natural shelter of the coastal waters, the impact will be different. Shallow north-facing shorelines are expected to see the highest swells and surfs; especiall for Barbuda and the more northerly islands. In open waters, the swells will be virtually harmless to small craft operators as they will be long-period, gentle waves. Again, this is no “swellmageddon”; however, there will be impacts and associated financial losses.

MONTSERRAT VOLCANO OBSERVATORY (MVO) WEEKLY REPORT FOR THE PERIOD MARCH 16TH TO 23RD, 2018

by Shirlian Queeley

Activity at the Soufrière Hills Volcano remains low.

The seismic network recorded one volcano-tectonic earthquake this week.

There have been no measurements of the SO2 flux since 12 March.

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.
