Atlantic Hurricane Season Discussion

[tron777]

TD 10 is moving N and not expected to bother anyone. Should get a name shortly.

TD 11 is now TS Julian winds of 50 mph moving to the NE. This one is also not expected to impact land.

The next African Wave looks to have an 80% chance to develop over the next 5 days.

TD 10 is still out there and still expected to get a name this week. Still expected to be a fish storm.

The next African Wave continues to look healthy and a medium to high chance for further development.

[tron777]

TD 10 is now TS Kate. Again, this one is moving N and will remain a fish storm.

TS Kate moving N with winds of 40 mph. The African Wave is almost ready to rock and roll.

[tron777]

Kate is weakening and down to a depression. In the next day or two, we can kiss her good-bye. Still watching the African Wave as our next potential trouble maker. NHC is expecting a TD in the next day or two.

[MVWxObserver]

The Wave off the African coast has been upgraded to TD 12.

[tron777]

TD 12 is expected to get a name pretty quickly. A hurricane also looks to occur with this system by very early Fri morning (per the NHC's intensity guidance). Looking out in time... a few models show a more westward track, but the bulk of the guidance has it going WNW then eventually more North so a fish storm basically. It's early in the game for TD 12 so I don't want to jump into any conclusions yet.

TS Larry is now born in the far Eastern Atlantic with winds of 45 mph. Larry is expected to become a major cane by late this weekend.

https://www.nhc.noaa.gov/graphics_at2.s ... t#contents

[tron777]

The last update from the NHC on TS Larry had winds of 50 mph. On satellite, you can now see an eye so I would expect a hurricane on the NHC's next update later this afternoon.

[tron777]

We've also got to watch this sneaky tropical wave in the SW Caribbean. If it can survive the trek across the Yuc. Penn. and get into the SW Gulf down the road, then we may have something to talk about there also. Currently, the NHC is giving it a 30% chance over the next 5 days.

https://www.nhc.noaa.gov/gtwo.php?basin=atlc&fdays=2

[tron777]

Larry has winds of 70 mph this evening. I was thinking a cane per my last post, but they've stuck with a strong TS. That's fine. Whatever.

A couple of the tropical models actually strengthen Larry to Cat 5 briefly. Looks like Bermuda will be a very close call - would be a bit nervous if I were there.

[tron777]

Larry still has winds of 90 mph as of the 11am update. Updated intensity forecast from the NHC: (Looks to be a Cat 4 down the road).

So far the CONUS looks to be okay as Larry remains over the ocean. The only landmass that should keep their eyes open is Bermuda. That island is not out of the woods yet.

Also watching a disturbance that has a 30% chance to develop in the next 5 days over the SW Gulf. A few models try and develop this thing and it becomes a problem for the Gulf Coast again in the future. We'll see... development, if it does occur with this one, is expected to be slow in the short term.

I saw the other day on TWC tropical update that hatched area forecast and thought, what is making that system take a sharp right turn after going through the Yucatan. Too bad its not forecast to shoot due west into Mexico proper and avoid the USA entirely. Last thing LA, MS, and other areas need is MORE rain after such massive flooding and destruction via Ida.

Agreed Bro. I'll root for a TX landfall if it comes to that versus LA. My customer has had about enough of it lol

[tron777]

Larry has winds of 120 this morning moving to the NW at 12. Larry will continue to be a major hurricane over the next couple of days. Bermuda is still at risk with this system but the CONUS can breathe a sigh of relief thank goodness.

Now, we should be turning our attn to that wave in the S Gulf. Still looking like a 30% chance over the next 5 days so development, if any, will be slow. Gulf Coast states still need to be watching it as some models still want to develop this thing.
