Joyce Forms, Issac Remains Weak in the Caribbean
TD#10 was upgraded to Tropical Storm Joyce, not affecting mainland land, but could approach Bermuda.
Isaac's track has not changed much, and the spread is still fairly much the same. All of Florida and the Gulf will need to watch. Isaac may be weak right now, but it is a very large system, and impacts will be felt a good distance from wherever the center passes. A large system is more capable of driving storm surge along the coast as well.
Strength wise, conditions are very good for intensification when, and if, it gets its act together.
7AM EDT Update 23 August 2012
Tropical Storm Isaac remains a large but disorganized Tropical Storm this morning, as recon failed to find an organized center overnight, and wind speed is down to 40mph. It seems to be still suffering from competing centers.
Today is a day of transition and not much will change with the future track, tomorrow becomes more interesting based on how close and how much time the system spends over Hispaniola. Conditions are expected to improve tomorrow, and Hurricane Warnings are up for Hispaniola, mainly in the southwestern part, and all of Haiti.
In the short term, jogs and center relocation will make getting a handle on the future track difficult, but the general pattern of the NHC's track seems good.
TD#10 will likely be upgraded to a Tropical Storm later today, and Bermuda is in the long range cone.
