Although one or two showers are in the forecast today, conditions are not favorable for shower activity as mid level dry air will suppress shower formation. Easterly winds will prevail at 10 miles per hour with high temperatures reaching into the middle 80s to the low 90s.
Wave heights will remain below five feet with wind speeds of around 10-15 miles per hour mainly from the east. There is a moderate risk of rip currents for the northern beaches of St. Thomas.
IN THE TROPICS
INVEST 94-L: A weak area of low pressure, associated with a tropical wave, located more than 900 miles east of the Lesser Antilles continues to produce disorganized showers and thundershowers. Some slow
development of this system is possible during the next day or two before upper-level winds become unfavorable for tropical formation. This system is expected to move slowly westward across the tropical Atlantic Ocean for the next several days.
Also, a tropical wave located just off the west coast of Africa is expected to move quickly westward during the next several days. Some slow development is possible late this week and over the weekend when the system is several hundred miles east of the Lesser Antilles. There is a slight chance of development over the next two days and a 20% potential for development through five days.
