Tropical Daily Planner – Atlantic

Atmospheric conditions across nearly all of the Atlantic basin are not conducive for tropical cyclogenesis. Even Invest 93L, a broad area of disturbed weather, is within an environment that is only marginally conducive for slow development. Favorable upper level ridging is centred inland over Central America. Therefore, moderate west to southwest winds aloft are likely to persist offshore across the western Caribbean Sea. Nevertheless, 93L may gradually organize and strengthen as it begins to move northward over the next few days. Surface pressures may lower a bit further due to non-tropical processes involving a dip in the jet stream between days 3-4. Unsettled weather conditions are likely to overspread portions of Cuba, the Bahamas, and south Florida regardless if full tropical development does occur.

Additional tropical development is not expected over the next five days.
