Invest 99L is forecast to strengthen into a TS in the next 48-72 hours.

1. UPDATED: Showers and thunderstorms associated with a tropical wave 
over the eastern Caribbean Sea are beginning to show signs of 
organization. Recent satellite-derived surface winds also indicated 
that a broad low pressure system has formed in association with the 
wave. Additional development of this disturbance is expected over 
the next few days, and a tropical depression could form during the 
next couple of days while the system moves moves westward at about 
15 mph across the Caribbean Sea.  Interests in Jamaica, Honduras, 
Belize, Guatemala and Yucatan should monitor the progress of this 
disturbance.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...60 percent.

99L has already been updated to have a 80% of forming into a TS in the next 5 days.

1. A westward-moving tropical wave accompanied by a broad low pressure 
area is located over the eastern Caribbean Sea just west of the 
Windward Islands. Associated shower and thunderstorm activity 
continues to show signs of organization, and environmental 
conditions are expected to gradually become more conducive for 
development. A tropical depression is likely to form during the 
next day or two while the system moves moves westward at about 15 
mph across the central Caribbean Sea.  Interests in Jamaica, 
Honduras, Belize, Guatemala and Yucatan should monitor the progress 
of this disturbance.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...80 percent.

Is it just me, or does it seem like these things always start out at 20%.... then 40%.... then 70%.... then 90%? Unless I completely misunderstand how this works, seems like 4 out of 5 of the 20% storms should peter out to nothing.

You completely misunderstand how this works. 

The percentages represent chances of a cyclone formation in the next 5 days, and not overall chances of formation.

That makes a lot more sense. Although I'd argue that it's not super useful when the shit's still over near Cape Verde.

the NHC is the Atlantic basin's official tropical cyclone tracking agency. They have to track every storm in the Atlantic.

The models have been hinting at a cold front into Texas sometime next week. It's still there this morning and the mets are starting to have more confidence that it will be for real. 

Although the primary benefit will be to drop temps and dewpoints and signal a start to fall weather, another benefit will be that it will be the first brick in the fall "forcefield" that protects Texas from tropical cyclones.

It's not 100% foolproof, but the odds go way down in Texas after the first front, so be cheering for that. 

Also, 40* dewpoints all the way to the coast. Gottdam bring it on.

I sure hope it's real. This one seems more reliable than the other ones, but there are a lot of disappointments in early September in Texas weather. 

I've been planning this week to start preparations for my pecan harvest. I sure hope there is a cool down when the work starts in earnest later in September.

I’ve read this may have something to do with the Super Typhoon in The Pacific right now. It’s forecast to track north which buckles some of the upper level jet patterns and allows for fronts to make it this far south. I think that is what I’ve read.

Getting a cool front through all of Texas by 9/10.  Feels early.  I hope it happens.  Spacecity weather guys swag a 50% chance right now of it happening.  I love summer every year until I don't.  I think I'm more ready for this one to end than others because of all the rest going on.

I agree with everything in this post.

Yep, I can handle it if I can get to the river for a swim a few days a week or go and sit at a nice bar with misters. This year just tired of no river, being stuck at the house, etc. 

2020 can lick my nuts.

99L has some opportunity to strengthen in the Caribbean before it buries itself in Central America

This turned out to be understated. Nana already has a closed eyewall (6 Miles wide Ned!!), and is going to strengthen right up until landfall. There is potential for a category 2 hurricane, and its not impossible she becomes a major.

Yeah, but she is going into Central America so nobody here cares. If this could front next week does come to fruition, we cold be done with tropical systems for the year. On the other hand, the front could be a self starter when it reaches the gulf and create its own tropical storm.

Nothing on the map now seems of much concern.

Of course Nana is doing exactly what we thought Harvey would do - and did, up to a few days before it decided to twist north and wreck the U.S..

However, the chances of any hurricane doing even a semi-close imitation of Harvey are infinitesimal so I'm sticking with no concern.

Trust me, people that are diving near Belize care.

Japan’s coastguard rescued one person in the search for a cargo ship carrying livestock that went missing in the East China Sea after issuing a distress signal during typhoon Maysak. The storm has killed one person in neighbouring South Korea and forced 2,000 others to be evacuated from their homes.

The Panamanian-registered vessel, called Gulf Livestock 1, sent the distress call from the East China Sea, to the west of Amami Oshima Island in south-western Japan, Japanese public broadcaster NHK reported.

The vessel departed Napier in New Zealand on 14 August with 5,867 cattle on board, New Zealand’s foreign ministry told Reuters.

A spokeswoman for the coastguard said one person was rescued on Wednesday night Tokyo time during the search for the ship after being spotted adrift wearing a life jacket.

 

Damn, 6K cattle

Bad anniversary, surprised no one noted it.

Today (Sept. 8th) is the 120th anniversary of the landing of the Cat 4 hurricane in Galveston.  Still the deadliest natural disaster in one event (some people put drought casualties above this, but it's hard to nail those down) in U.S. History.

What most people don't know about this storm is that it actually (and very, very uncharasterically) strengthened again after moving inland.  It lost its full-blown tropical characteristics, but went from 30 mph gusts over OK to tropical storm strength over the Midwest, and by the time it got to Ontario and Buffalo, was equivalent again to a Cat 1 storm (although again, "officially" it was no longer a hurricane).  It virually wiped out the New England apple harvest, and winds were so strong on Lake Champlain that on the Vermont (west) side, the water in the lake receded out some 200 yards, and the New York (east) side had 20 foot waves and significant flooding - in freaking Vermont.  It killed somewhere between 300-500 in eastern Canada, making the storm the 8th deadliest natural disaster alone in Canada.

It was in most ways, from start to finish, still probably the worst storm to hit North America ever.
