You’re officially the chaser for TD for Sally. Report all interesting things you see.
Be safe, man.

I've been tracking that yellow "X" in the SW of the NOAA gulf tropical chart and it looks like that system is the remnants of Marco. It looks to move N along the coast and develop into a hurricane next week. Thanks for your reply!

It’s not Marco. Had nothing to do with it.

Out of the loop, is she still moving slightly due East of North? Another half H to the right or no?

You may not they are very near as we speak

Recon about to confirm the movement. It was due north by the end of the last recon.

He made the exact same LSU OLine comparison in that thread.
I was hoping someone would catch the gag.

The HWRF is a weather model used by the National Hurricane Center to forecast movement and intensity of tropical systems.
In this case the output of the model is forecasting that Sally will have a central pressure of 972 milibars and will be near the Alabama coast in about 6 hours.
The current central pressure is 979 millibars. As the central pressure decreases the wind speeds near the center increase since wind is created by the difference in pressure over distance from the center going outward.
In other words, pressure dropping = stronger winds. A 7 millibar drop could be about a 15 to 20 mph increase in maximum winds depending on the structure of the storm.

What does this mean exactly? Thanks for your posts!

I’m periscoping my pitiful back yard.

Latest report is 80 mph sustained winds.
Guessing an increase could put it at 90-95mph mid to high cat 1.

I saw some radar estimated 92 mph winds on the eastern side of the eye. That's just radar estimated, though.

It's a dirty eye, but an eye.
Drop on the SW of the storm shows the air flowing in isn't very dry. That's not going to be a hindrance.

Have to wait for it to be offical but pressure is dropping in the first pass

976-977 based on the xtrap pressure.

972.6 from the recon

Suppose to head to perdido key on Friday. Chances thing will be cleared up by Friday?

Yeah the HWRF and HMON were showing 80 to 85 knots in a few hours before it starts interacting with land.
Extreme convection on north and west sides of center...bottom half has filled out nicely (for the storm) also

Getting down right gusty here in Slidell

That's about what I imagine a solid Cat 1 to look like in my head.
