A tropical wave is moving through the eastern Caribbean and is bringing rain and occasionally gusty winds to Puerto Rico and the island of Hispaniola (the countries of Haiti and the Dominican Republic). Because of strong upper level winds and interaction with these land masses, it is not expected to develop in the next day or two.
A piece of the tropical wave that moved through the Lesser Antilles has broken off into a trough of low pressure currently located near the Bahamas. It and its moisture are being drawn northward along the frontal boundary near the East Coast by the upper trough over the Eastern U.S. While it is not expected to develop into a tropical cyclone, the moisture from this trough is expected to spread up the front and may bring an enhancement to rain chances along the East Coast--possibly into New England later this week.
In the Central Pacific, a weak trough of low pressure about 1300 miles southwest of Hawaii is being watched. Although this trough is over warm waters, upper level winds are currently not favorable for development.
