Keeping an eye on Isaac as watches are issued for Lesser Antilles Islands
By Eric Zernich From KATC ABC
As Isaac continues its track towards the Lesser Antilles islands hurricane watches have been issued for Dominica, Guadeloupe and Martinque, while Antigua and Montserrat are under a tropical storm watch.
Tuesday morning Isaac has encountered some westerly wind shear weakened the system slightly down to a strong tropical storm with 70 mph winds.
Isaac will continue its gradual westerly motion in the coming days and slide over warm waters and runs into a more favorable environment allowing Isaac to maybe restrengthen to a hurricane again on Wednesday.
But after reaching hurricane strengthen the National Hurricane Center forecasts Isaac to be downgraded to a strong tropical storm as it makes landfall with the Lesser Antilles Islands Thursday afternoon.
However, there are still a lot of uncertainties as far as the intensity with Isaac in the coming days which is why some of the islands have issued hurricane watches.
After pushing into the Caribbean Sea this weekend Isaac is project to slowly weaken but remain a strong tropical storm.
Looking at the extended spaghetti plots for Isaac shows all the uncertainty with this storm but a few more models are trying to take Isaac into the Gulf of Mexico so we will have to keep an eye on this storm into next week.

That said our main long range GFS and European models do not show Isaac making it into the Gulf but rather staying on a westerly track into Central America.
One thing that might help us next week to keep Isaac to the south is the long range models are hinting at maybe our first fall cold front of the season which would push the storms away from Acadiana.
But that is 10 days out so things are likely to change in the coming days so we will be watching the models and keeping you informed with the latest information.
