Here’s the 945pCDT/1045pEDT rain radar (top view) & wind velocity (bottom view...brighter colors = faster winds, duller = slower, the color choices (red/green/etc) represent the direction in relation to the radar site). That bright ring around the clear calm center/eye is the main band of winds. That’s the Cat4. Less winds outside that ring.

Louisiana Governor John Bel Edwards has shut down I-10 from the TX/LA line to the Atchafalaya Bridge... He expects Cameron Parish to look like the Gulf of Mexico for a couple days... the Cajun Navy is undermanned thanks to Covid and its own evacuations in SW Louisiana...

is it just me or do I think that the northern eyewall is the one to fear, especially right now... I think maybe later the storm might be a little more even but the northern eyewall looks much worse than the southern eyewall at the moment... just checked the latest surf forecast for Holly Beach, and those are going to be 15 ft waves for 12 seconds, massive...

Almost looks like it jogged north last hour from its NNW move. Center is almost there. Conditions deteriorating by the minute. Tornado warnings are the red boxes.

I think what we're seeing is the Northern eyewall is blocking the radar returns so it looks like South side is open, but on satellite it's a nice doughnut. But we'll know for sure once it comes in. Should go right over NWS Lake Charles radar site...we'll see if it survives.

Surge obs Wed 26Aug 11-ish pmEDT/ 10pCDT

We only have a few gauges in these regions.

Listed East to West from near New Orleans to just S of Houston. Values are my own interpretation of the gauges from here: https://tidesandcurrents.noaa.gov/in...orm/Laura.html Values don't represent peak unless specifically stated, some areas are in low tide, others just out of low tide. Biggest surge comes as the eyewall comes ashore.
Louisiana:
-Pilottown: +1ft, rising
-Grand Isle: +3.5ft, quickly rising, minor flood stage
-Eugene Island: +3.8ft, rising, minor flood stage
-Freshwater Canal Locks: +4.5ft, rising, Moderate Flood stage
-Lake Charles: +2.5ft, falling (low tide)
-Bulk Terminal (Just SW of Lake Charles): +2.8ft, steady (low tide)
-Calcasieu Pass: +4.1ft, quickly rising, Minor/Major flood stage

Texas:
-TX Point/Sabine Pass: +3.1ft, steady, Moderate/Major flood stage
-Port Arthur: +2.7ft, rising, minor flood stage
-Rainbow Bridge (NE of Port Arthur): +2.3ft, steady
-High Island: +2.6ft, steady
-Rollover Pass: +3.1ft, steady
-Morgans Point: +2.4ft, steady
-Eagle Point (Galveston Bay): +3.3ft, rising
-Galveston Bay Entrance, North Jetty: +3.4ft, quickly rising, Moderate/Major Flood stage
-Galveston Pier 21: +3.8ft, quickly rising
-Galveston Railroad Bridge: +3.4ft, rising
-San Luis Pass: +3.4ft, rising, Minor/Moderate flood stage
-Freeport Harbor: +3.3ft risin, Moderate flood stage

The rate of rise in surge height right along the Gulf coast from TX/LA border to Eugene Island, LA is increasing.
