Tropical Storm Chantal has formed over the south-central Atlantic. Chantal is speeding along and will approach the Lesser Antilles on Tuesday (as a tropical storm). The long range forecast cone, provided by the National Hurricane Center, is very "narrow" while models are in general agreement of where Chantal is going. Over the next few days, the system is expected to cross into the eastern Caribbean and interact with the Lesser Antilles (and the Greater ones, too!). Many of the Caribbean island nations will deal with the wind and squally rains associated with Chantal. The good news? it appears as though the system will "stay in check" and not rapidly grow into a stronger system as the week continues. The reason that Chantal is likely to remain a minimal tropical feature is due to increasing wind shear as it veers more to the north. Strong upper winds will make it unfavorable for Chantal to become too powerful. Still, very unsettled weather conditions will overspread the islands and (eventually) aim toward Cuba, the Bahamas, and Florida (if it holds together). Stay tuned!
By the way, regardless of Chantal's potential influence on our weather... later in the week... south Florida will see more wet weather by Tuesday. An upper low (high in the sky) is spinning near the Bahamas and drifting our way. Keep in mind that it's a Non-Tropical weather feature, but the instability it brings can lead to numerous showers and thunderstorms. There's also the potential for gusty winds and small hail... since upper lows consist of a cool pocket of air, high above us! (The Heat and Humidity will hold, though).
