6 to 10 inches is bad enough but if spread out over time may not be a huge problem.


See that dot in Orleans Parish that calls for 14"?

Basically on the NHC path too. Still too weak I think but the idea is pretty solid at this point.

So my phone just showed a Hurricane Watch for Ascension parish, expiring at 1 am tomorrow? No other surrounding parishes, just us. Is this a glitch with the app?

Meh... Laura was supposed to flood Lake Charles enough to move the coast line to Beauregard Parish. Didn't happen.

GFS track did shift a little east from GI to the River but not really significant at this point.

Now when it gets close to landfall, that 20 to 30 miles will make a big difference like it did for Laura.

Policing the board is more lame as frick.

I know you’re kind of being tongue in cheek, but we have to watch that line of thinking. That COULD have happened. And I also know it was a scare tactic to get people to leave. But we all know those storms can drop tons of rain and water in a short period of time.

All I’m saying is you can’t let your guard down when it comes to water.

You guy is coming in Tuesday to give me an estimate on all my work. Everything but the flooring, more than likely. Had someone else lined up for that already. But I have a ton more to do outside of that.

Yep. From how things are looking and GFS's trend to the weaker end so far this year, a strengthening 2 at landfall seems possible.

Ascension is under the hurricane watch. It's more for the far east parts of the parish though. It will expire later than that though.

Strengthening 90 mph is what I'm thinking at this point. Might be a little conservative though.

From Brian Tang @btangyWx (another good Twitter follow):

quote:

The last several runs of the HWRF have had a pretty consistent signal for Sally undergoing RI beginning late Sunday into Monday. There are some signals that support this possibility. (1/5) LINK


quote:

First, the upper-level flow looks to become favorable for intensification. There will be a cutoff low to the SW of Sally, an upper-level trough to the NE of Sally, and an anticyclone over Sally. This flow pattern will result in low wind shear. (2/5) LINK


quote:

Additionally, this cutoff-trough pattern is reminiscent of the RI composite for the NE-trough cluster from @MikeFischerWx et al. (2019), so we know this kind of upper-level pattern has been associated with past TCs that have undergone RI in similar environ. (3/5) LINK


quote:

Second, the midlevel environment around Sally looks to be fairly moist. The tropical wave in the central Gulf of Mexico is helping to moisten the environment to the west of Sally. Greater moisture upshear is associated with a higher probability of RI. (4/5) LINK


quote:

Like with Laura, we are again faced with the possibility of a tropical cyclone undergoing RI as it approaches the coast ??. Hopefully Sally doesn't. Regardless, the forecasted slow movement will be problematic for surge and flood hazards. (5/5)

St. Bernard Parish here. Inside levee. 90 mph is normally stay for me. Hearing “strengthening 90 mph” worries me
