A low pressure system east of the Lesser Antilles is becoming better organized as it approaches the region at about 15 to 20 miles per hour or 24 to 31 kilometers per hour.

Regardless of development, this system is expected to produce adverse weather conditions over Saint Lucia beginning tonight, Aug 17.

The Saint Lucia Meteorological Services is therefore issuing a severe weather warning for Saint Lucia with effect from 6 p.m. today, until further notice. Associated with this low pressure system are moderate to heavy showers, gusty winds, thunderstorms and rough seas.

Rainfall estimates of 20 to 40 millimeters per day and a maximum of 75 to 125 millimeters can be expected over the Windward Islands during the next 24 to 36 hours. Wind gusts up to tropical storm strength are possible and rough seas with waves and swells averaging 7 to 9 feet or 2.1. to 2.7 metres are also expected with the passage of this system.

As a result, residents and motorists, especially those in areas prone to flooding and landslides, are urged to exercise extreme caution in their activities. Small craft operators are advised to remain in port, other marine interests are advised to exercise caution, and residents are advised to keep away from the beaches.

All residents of Saint Lucia are asked to pay attention to further announcements from the Saint Lucia Meteorological Services and NEMO. The Saint Lucia Meteorological Service will continue to closely monitor this feature, and issue additional statements as necessary.
