A surge in low-level moisture associated with a weak tropical wave may lead to the development of one or two showers throughout the day today. Rainfall accumulations will remain on the light side. A drier weather pattern should prevail by Sunday afternoon as a result of dry Saharan air entering into the local area. This air mass is expected to hold through late Monday night. Today’s high temperatures are forecast to be near the middle 80s to the lower 90s.
Across the regional waters, five foot seas with winds to 15 knots (17 miles per hour) are expected. There is a moderate risk of rip currents for most of the beaches of St. Croix, and for the northwestern beaches of St. Thomas.
IN THE TROPICS
Showers and thundershowers associated with a small area of low pressure located about 1,050 miles east of the Windward Islands are showing some signs of organization. Environmental conditions appear conducive for additional development, and a tropical depression is likely to form over the weekend or early next week while the low pressure system moves westward to west-northwestward at 10 to 15 miles per hour. Conditions appear less favorable for development when it reaches the Lesser Antilles and eastern Caribbean Sea by the middle of next week. There is a 60 percent chance of development over the next two days, and a 70 percent chance of development through five days. A more detailed tropical weather discussion will be provided later this morning.
