Tuesday Morning Update

Zeta weakens some

The Weather Situation
Zeta will become a hurricane again after weakening over land last night. Outflow appears excellent by the appearance of the high clouds. IMO, Zeta is currently weaker than 70 MPH, and I believe it is closer to 55-60 MPH.

Wednesday Night Update

Zeta moving inland

The Weather Situation
Zeta made landfall on the southeast coast of Louisiana at around 4 PM CDT. Golden Meadow, LA reported at wind of 94 with a gust to 110 mph. Bayou Bienvenue reported at sustained wind of 88 mph and gust to 112 mph.

Flash flooding, wind damage and isolated tornadoes are possible along the track. Official estimate of sustained winds at landfall were 110 mph. At first glance this looks to be an overestimate as gusts should be found in the 130+ mph range.
