This is having a small impact on Rita, but this doesn’t appear to be the only thing working on her. The upper low over the Bay of Campeche is also adding in a slight northern jog. I don’t feel either of these is strong enough to turn the storm towards SELA. But with the turn starting sooner then later I am concerned again this evening after wavering this morning… I am back to the TX/LA border area. Lake Charles be ready!!!!!!
Let’s get to some intensity stuff, she will clearly be a strong Cat 5 tonight and may slightly weaken tomorrow. I don’t see her weaken more then a Cat 4 before landfall. Which means she will have a huge surge because of her time as a Cat 5 tonight and tomorrow and maintaining Cat. 4 strength until landfall the surge will be built up. That means areas From Corpus Christi to Lafayette need to be ready for a potentially huge storm surge. Areas from Assumption Parish right thought the tidal lakes will have above normal tides and a surge possible as high at 6-7’. Shes big and pushing a lot of water.
Track forecast still seems on track but, worry that such a large powerful storm can never be handled well by numerical modeling. That along with this ever so slight WNW movement now for about 3-5 hours makes me lean right of the NHC forecast track. I think Galveston to Lake Charles should treat this as a mandatory evac from a Cat. 5 storm.
