7/12 – Rob Knight’s “TS BARRY IMPACTS” Weekend Forecast

Tropical storm Barry is currently located about 55 miles SSW of New Orleans moving to the NW at 5-7 mph. TS Barry will eventually make landfall on the southern Louisiana coastline early Saturday morning as a TS or barely a CAT 1 hurricane.

The main threat for this system is heavy rainfall beginning early this into Sunday. Rainfall amounts will be especially high along and east of the storm track. Forecasted rainfall amounts range from 5-15″ across the forecast area this weekend with significantly higher local amounts possible. In addition, intense rainfall bands can set up as the storm moves further northward, which can cause intense localized flooding and high rainfall rates. The strongest winds are expected to be 65 knots with higher gusting amounts, especially along the central Louisiana coastline.

Here in south Mississippi I believe we will have winds much lower at 15-25 mph with periodic higher gusts into the upper 30 mph range. In addition to those main threats during the storm, there is a secondary threat of isolated tornadoes Friday into Saturday morning mainly to our west in SE’tern Louisiana. These tornadoes would be weak, but there is increasing confidence in the possibility for tornado development, especially ahead of this system. Overall, the main threats for this tropical system are heavy rainfall, gusty winds, and storm surge with a secondary threat for tornadoes ahead of the storm.
