…. Tropical Cyclone Ernesto Update (#2) ….

…. Ernesto Looking a Bit Weaker and More Disorganized ….
…. Overall Forecast Track Through 5 Days Shifted More Southward ….
…. Based on Current Forecast Track, Threat to Middle and Upper Texas Coast Decreasing ….

On this Sunday morning, westward moving tropical cyclone Ernesto.. currently of tropical storm strength..
is centered over the Caribbean Sea about 240 miles SE of Kingston, Jamaica.

The current forecast intensity/track.. as prepared by the hurricane specialists at the NWS/National Hurricane Center..
suggests that the system will continue westward through the Caribbean Sea over the next day or so before turning
a little more west northwestward in the western Caribbean thereafter. Please note that this turn to the west northwest
isn’t as distinct as it was in earlier advisories. In addition, with a more disorganized storm compared to 24 hours ago..
strengthening to hurricane intensity isn’t forecast to occur until late Tuesday night or early Wednesday as the system
moves onto the east coast of the Yucatan peninsula.

You can see the NHC forecast track.. through the next 120 hours/5days.. at this link:
(This link will remain active and updated through the life of Ernesto.. so keep this link handy)

NHC forecasters continues to point out that there is considerable uncertainty regarding the forecast track and intensity beyond
the two to three day part of the forecast. As a result, while it is too early to say where Ernesto will ultimately end up and how
strong it’ll be when it gets there, it should be pointed out that the continued southward shift in the NHC forecast track does
greatly reduce the threat that the system will end up, with time, in the central gulf of Mexico and further reduces the threat that it will end
up in the northwestern Gulf of Mexico. It increases the threat to the Bay of Campache and the southwest Gulf of Mexico and
ultimately to areas along the east coast of Mexico and perhaps as far north as far south Texas with potential landfall following
by Friday into next weekend.

All interests around the western Gulf of Mexico, especially from the Mexico coast northeastward across the lower Texas coast
should be paying close attention to the advisories and updated track and intensity forecasts from the NWS/National
Hurricane Center as it regards potential impacts for late in the coming week into next weekend.

I’ll continue to monitor this system closely.
