A surface trough located north of the region will maintain a light easterly wind flow today. This trough, combined with daytime heating could lead to the development of one or two showers today. Daytime high temperatures will be in the upper 80s to low 90s.
Seas to six feet and winds to ten knots are expected. A north-northwesterly swell is creating choppy seas along the northern waters and local passages. Small craft operators are urged to exercise caution. There is a moderate risk of rip currents for some beaches along the north and western coasts of St. Thomas and St. Croix, as well as at Cramer’s Park also on St. Croix.
IN THE TROPICS
A tropical wave, accompanied by a broad area of low pressure, is producing a large area of showers and thundershowers over portions of western Africa. This wave is expected to move off the coast later today, and although tropical development is unlikely this late in the hurricane season, some development of the system is possible during the next few days while it moves westward to west-northwestward toward the Cape Verde Islands. Strong upper-level winds should prevent additional development by mid-week. This weather system is not expected to impact the Caribbean region or the Virgin Islands.
