Tropical Storm Barry Heading for Louisiana Coast Heavy Rain Threat Continues

 

Tropical Storm Barry Heading for Louisiana Coast Heavy Rain Threat Continues

Tropical Storm Barry continues to remain just that, a tropical storm with an elongated east west structure. While conditions remain favorable for strengthening time is beginning to work against this as the west northwest drift  brings Barry closer to the coast. Gulf water temperatures are in the mid 80s and certainly supportive for strengthening as are favorable outflow conditions aloft. However we are talking about another 24 hours or so before landfall takes place somewhere in Southwest Louisiana. Top winds are 50 mph. The main issue here is going to be heavy rains that could last for several days or longer once the storm is inland due to weak upper air steering conditions.

REGIONAL RADAR

On the regional and local radars this morning there isn’t much going on rain wise other than some bands of rain coming into rain soaked Southeast Louisiana but not much happening further west toward Lake Charles. That east west structure is keeping most of the heavy rain offshore for the time being.

With landfall coming over the weekend and the very slow steering currents aloft we are going to see soe rather extreme rainfall amounts of 10 to 20 inches in some places and as we mentioned some areas in Southeast Louisiana have already gotten several to many inches already from the wet pattern across the Gulf States all week long.

The upper air pattern does not favor any of Barry’s moisture heading our way as the upper air jet stream pattern is not conducive to a flow from the southwest nor is there anything upstream in the overall pattern to bring the rain to the northeast. Barry will likely just rain itself out over the lower Mississippi Valley over the weekend and early next week.
