At 4:30 this afternoon the Barbados Meteorological Services issued a severe weather statement for Barbados.

An approaching tropical wave with axis now near 49/50°W and associated with the remnants of Tropical Depression Kirk, will begin to affect Barbados late tomorrow into Thursday. The system which is tracking westward at between 20 and 25 mph (32 to 40 km/h), has been fluctuating in intensity and some re-development is possible as it approaches Barbados and the Windward Islands late tomorrow.

This could require the issuing of a Tropical Storm watch or warning for Barbados at late notice.

Regardless of development, sustained surface winds of between 25 to 35 mph (40 to 55 km/h) with higher gusts are expected to spread across the island starting tomorrow night and persisting into Thursday.

In addition, pockets of moderate to heavy showers, periods of rain and scattered thunderstorms are expected. Rainfall accumulations of at least two to four inches (50 to 100 millimetres) are possible between Wednesday night and Friday morning. Some flash-flooding is likely in low-lying areas. Thus, residents are urged to be on the alert and take all necessary precautions.

Large easterly/south-easterly swells of 3.5 to 4.5 (11 to 15 ft) are also forecast to accompany the system. These adverse sea-conditions are expected to persist into the week-end when northerly swells being generated by Post-Tropical Cyclone Leslie in the north-central Atlantic, propagate southwards across the Lesser Antilles.

Large waves and dangerous rip-tides can be expected. These will create unsafe conditions for small-craft operators. Sea-bathers and other users of the sea are also advised to stay out of the water.

Thus, a high-surf advisory and small-craft warning will be in effect from 6 a.m. Wednesday, September 26, until 6 a.m. on Monday, October 1.

A small-craft warning means in this case that mean wind-speeds of 25 to 33 knots (47 to 62 km/h) and/or seas equal to or greater than 3m (10ft) will be affecting the marine area.

A high-surf advisory is issued when breaking wave action poses a threat to life and property within the surf zone.

This information will be updated at 4 p.m. tomorrow or sooner if conditions warrant. (PR)
