Ya much more rural considering the alternatives. Still very flat....that surge can go an awfully long ways inland...

(This is the 11aEDT/10aCDT potential surge map that has a 1 in ten chance of being exceeded. So plan to and hope for less map, final track will determine final heights but will be high across a huge swath.)

And Levi of Tropical Tidbits mentioning the larger size results in slower intensification but sets it up to be healthier for later and may see increase in the strengthening by tomorrow.

Storms finally building on the previously empty SW side of center, attempting to close its center off (healthy step for storm)

Tue 5pEDT/4pCDT
Winds 80mph(130km)
Moving WNW 17mph(28km/h)
Pressure 990mb
Center about 480miles(770km) SE of Lake Charles, LA
Center about 510miles(820km) SE of Galveston, TX
Hurricane winds extend up to 45miles(75km) from center, TS winds 175miles(280km)

No changes. Just slight bump up in winds as center continues to better organize. Expected to intensify & Landfall Wednesday night / early Thurs. NHC states to remember that the average error in track of storm 36hours out is around 60miles, don't focus on an exact point, shifts are possible and wide reaching impacts. Average 36hour error in intensity forecast is 10mph.

With flat land and lots of water ways, on surge NHC mentions “This storm surge could penetrate up to 30 miles inland from the immediate coastline in southwestern Louisiana and far southeastern Texas.”
