On Sunday evening, the National Hurricane Center began issuing advisories on Potential Tropical Cyclone Seven in the western Caribbean. Moving into an increasingly favorable environment for further development, this is likely to become Tropical Storm Franklin within the next 24 hours. Tropical Storm warnings are now in effect for the Yucatan Peninsula, as impacts in that area may be felt as early as Monday afternoon. From there, this system should move across the Bay of Campeche and into eastern Mexico late Wednesday into early Thursday. Heavy rain and gusty winds are likely in the aforementioned areas, but at this time, no U.S. impacts are expected.
We also continue to monitor the progress of Invest 99L in the central Atlantic. As of Sunday night, convection was almost non-existent around the disturbance, and the National Hurricane Center continues to lower its expectations for development in the short-term. It has a very tough road ahead of it thanks to strong upper level winds, but it still bears watching as it moves WNW over the next week or so.
