At 8:00am Invest 98L was located at 14.2N, 43.6W, about 1250 miles east of the southern Lesser Antilles. Shower and thunderstorm activity associated with this low pressure system has continued to become better organized since yesterday. Satellite data also indicates that the low's circulation is gradually becoming better defined. If current trends continue, a tropical depression is likely to form later today or tonight while the low moves westward at around 20 mph.
At 11:00 a.m., the center of what was Tropical Storm Danny was located near latitude 16.0 degrees north, longitude 62.0 degrees west or about 220 miles east-southeast of the British Virgin Islands. The low pressure system is moving toward the west near 12 miles per hour (mph). Maximum sustained winds are near 30 mph with higher gusts. The trough is expected to dissipate in a few days.
Danny is down to a 40 mph tropical storm and could weaken to a depression over the next 6 hours. It should weaken to a remnant low or tropical wave in 24 hours. Only minor impacts from heavy rain in squalls are possible. Sustained winds are expected to peak in the 20-25 mph range, with gusts to 35 mph possible. No significant impacts are expected.
The centre of circulation is now exposed and environmental conditions will remain unfavourable as Danny tracks toward the northeastern Caribbean. Due to a recent southwest shift in the track, forecasters have adjusted the projected path further south. As a result, the overall forecast implications for the northeastern Caribbean is less wind and slightly less rain than indicated in the previous forecast. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Weakening is expected during the next 48 hours, and Danny is expected to become a tropical depression tonight or Monday. Tropical Storm Danny should be in the vicinity of the BVI tomorrow with increasing cloudiness, strong gusty winds, showers and thunderstorms. The winds could cause some isolated power outages.
