Wx: A tropical wave traversing the Eastern Caribbean with significant moisture and instability will result in cloudy to overcast skies with showers and thunderstorms from the Leeward Islands south to Trinidad and Tobago. Some heavy downpours will affect the southern islands all day while there is a good chance of some developing across the Leeward Islands this afternoon and tonight. Meanwhile, instability associated with an upper level trough over the Western Caribbean will trigger some cloudy periods with mainly localized and sometimes heavy showers and afternoon thunderstorms over Hispaniola. A stable airmass and an atmosphere low on moisture will yield little shower activity under partly cloudy skies over the rest of the Eastern Caribbean.
