While the upper low over the central Tropical Atlantic is no more, a strong westerly shear dominates much of the region with no development expected over the next three days. A trough over the Caribbean Sea is producing strong southwesterly shear from Cuba on through the Leeward Islands. Meanwhile, disturbances coming off the African [...]

The upper low that has inhibited the development of any tropical disturbance over the Atlantic continues to weaken and move towards Europe this morning.

This morning I’m preparing for one impressive heavy rain event for the entire forecast area. Is this the drought buster everyone has been waiting for? I think so! However, with the heavy rain comes the threat for significant flooding and possibly some wind damage. Meanwhile, the pattern change will not [...]
