Tropical development continues to be slow in the Dominican Republic/Puerto Rico region. Higher elevations of the W. Greater Antilles have taken their toll on the system currently being investigated (Invest 96L). Intensification, however, is expected today-tonight as it moves into the Bahamas region before turning northward as seen here on model guidance. The track is still sprayed pretty wide but the near-mean average over the immediate future takes it towards the east coast.
While a re-curve is still anticipated at some point, it’s becoming more apparent that this system “could” pass just close enough to New Jersey to bring some rain, wind and coastal flooding early to mid-week. That would probably be the most western solution of possibilities but it’s on the table. Should the system take a track that’s a little more east, we might just be on the hook for rough surf. Anything between those two scenarios is possible. Here’s the latest update from the NWS National Hurricane Center, straight from air recon:
SPECIAL TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 1025 AM EDT SAT AUG 23 2014 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Special outlook issued to discuss results of aircraft reconnaissance mission. 1. Updated...Reports from an Air Force Reserve Hurricane Hunter aircraft and satellite imagery indicate that the disturbance located near Hispaniola continues to lack a well-defined surface circulation. As a result, advisories are not being initiated at this time. However, environmental conditions are favorable for the development of a tropical depression or tropical storm later today or Sunday. Another Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the system this afternoon. This disturbance is forecast to move west-northwestward over or near the southeastern Bahamas today, and over or near the central Bahamas Sunday and Sunday night. Heavy rains and gusty winds are expected to continue over Puerto Rico and Hispaniola today. Winds to tropical storm force and heavy rains are expected to spread over the southeastern Bahamas, the Turks and Caicos Islands, and the central Bahamas through Sunday night. These rains could cause life- threatening flash floods and mudslides, especially in mountainous areas of Hispaniola and Puerto Rico. Interests in the Turks and Caicos and all of the Bahamas should monitor the progress of this disturbance, since tropical storm watches and warnings could be required with little advance notice. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...90 percent.

I wouldn’t be surprised if this forms into a named storm later tonight/early tomorrow AM. It’s entering a very favorable environment for intensification. One thing to keep in mind is that if this does come up the coast towards NJ, it will likely be weak from so much interaction with coastal SE US land. Coastal flooding after a week of onshore flow would be the headline, not the breezy-windy showers that would accompany such. I’ll continue to monitor this system very closely. Be safe! JC
