Re: Isaac Lounge

For all practical intents and purposes, Isaac appears to behave like an off-and-on TD since its Final Advisory was written.

More recently, the old, primary LLC has become prominent again, with scatterometer passes showing a well defined surface circulation, but with visible satellite confirming only somewhat organized deep convection. However, trends this afternoon suggest that with the LLC now exiting the region of higher shear that exists over the central to eastern Caribbean, convection may be getting better organized, and it is looking more possible that Isaac may end up a TD or even a tropical storm again.

Movement the past two days has been towards the west-northwest to northwest. Interests in Hispaniola, Jamaica, Cuba, Yucatan peninsula and the Lower Keys may want to monitor this system closely. Heavy rains and gusts to tropical storm force are already occurring regardless of classification.
