See the forecast lounge for more speculation on this system.
Satellite Image Offshore as of 6/29/2026:
Arthur's main impact was extreme amounts of rainfall in Louisiana, Mississippi, and Alabama, and a few other places. Near and inland along the Mississippi Gulf coast in particular, the rainfall amounts were something not seen in many many years in that area, causing all sorts of freshwater flooding.
We'll be watching the tropics into July.

Potential Tropical Cyclone One Issued Near Texas Gulf Coast
Posted: 10:50 AM 10 June 2026 | 2 Comments | Add Comment | Newest: 11:51 AM 15-Jun EDT
PTC ONE is producing sustained winds into tropical storm force based on buoy, ship and oil rig reports. Recon is now flying in. The cyclone at this time resembles a sheared tropical storm and it would not be surprising if we have Arthur at 10AM.
Ciel
4:00AM CDT 17June, 2026 Update
PTC ONE is a highly-sheared cyclone this morning, and too void of convection near and over the center for it to be classified as a Tropical Cyclone. However, with PTC ONE, as has been mentioned here, there and everywhere, the classification isn't what matters, but rather the impacts.

PTC ONE is already on the cusp of being classifiable as a Tropical Depression and may go straight to being a named Tropical Storm within minutes or hours after moving offshore. A Tropical Storm Warning is now up for the coast of Louisiana from Sabine Pass to Morgan City. There are a few models that increasingly suggest likely-Arthur may have a chance to strengthen a little more than forecast, so mariners and those along the coast may want to take note. Additionally, interactions with strong jet dynamics and a very large area of "brown ocean" (very saturated land and a humid atmosphere) could keep likely-Arthur going - perhaps even intensifying - over land. This is a very dangerous storm.

NHC will initiate advisories on Potential Tropical Cyclone One (formerly AL90) located over southern Texas, at 1000 AM CDT (1500 UTC).
8:00AM CDT 16 June, 2026 Update
Invest 90L is over land and still has a 60% chance to develop. The energy is stretched out along the front, but the best track position has it located there northwest of Brownsville near Encino, TX. This area has a chance to develop once it reaches the water, but anything that does (if it does) is likely to be short lived. The impact remains heavy, flooding rainfall.

1:40PM CDT 15 June, 2026 Update
The Area of Interest has just been Invest-tagged, 90L. Specialized model runs will begin shortly and recon is being tentatively scheduled.

Ciel
1:00PM CDT 15 June, 2026 Update
Chances for development of this system are up to 50%, and Tropical Storm Watches and Warnings could be issued as early as tomorrow for portions of the NW Gulf.
12:00PM CDT 15 June, 2026 Update
Widespread flash flooding, some of it catastrophic, continues. WPC has greatly expanded the MODERATE RISK outline

4:45PM CDT 14 June, 2026 Update

The risk of Flash Flooding across the south is going way up in response to the abundant influx of deep, tropical moisture courtesy of the area of low pressure we have been tracking and which is now inland over northeastern Mexico feeding into and interacting with an approaching wind shift front that is forecast to pull up mostly stationary for several days. Ground will likely become saturated if it isn't already across portions of south Texas, southeast Texas and Louisiana, and a multi-day, life-threatening flood event may be setting up.
Ciel
10:00AM CDT 13 June, 2026 Update

Above: This morning's visible image of the Gulf Low overlaid with GFS-analyzed 10-meter winds cr. TC-ATLAS
The Low in the western Gulf continues to gradually become better organized and is now likely centered just east of Tampico, MX, heading generally NW to NNW. Fluctuations in its path are likely over the next 3-7 days, but it is mostly modeled to head inland and then either track just inland from the coast of Texas, bumping into an approaching front, or reemerge off the coast roughly east of Brownsville, TX early next week.
The greatest risk with the area of low pressure in the western Gulf is going to be from the potential for several days of tropical rainfall and flooding, regardless of whether or not it becomes a Tropical Depression. The same will be true should it become a Tropical Depression, but never get a name. This is a system that is cranking up loads and loads of moisture into eastern Mexico, Texas and Louisiana, is likely to get stuck underneath a stalling front, and then get wrung out over the course of 3-7 days over many of the same areas. Flooding is always a serious risk with 'weak' systems that slow down or stall, but unfortunately, all-too-often these systems do not get the attention they deserve because they lack a name or title.
-Ciel
7:45AM CDT 12 June, 2026 Update
An area of low pressure has indeed formed in the Bay of Campeche. This is a very favorable region for Tropical Cyclogenesis and despite less-than-ideal conditions for development, development is possible and in fact the odds appear to be going up. An Invest tag is likely coming, specialized model runs would be added, and perhaps recon will also be tasked, depending.

Original Update
The 8am update for the tropical weather outlook now has the first area of interest for the 2026 Atlantic Hurricane season. This area would be the remnants of Cristina in the East Pacific after it crosses Guatemala and Mexico, which has a lot of high mountains. It's overall unlikely to develop, but worth watching in those areas and later on in the Gulf side of Mexico, and rainfall could reach its way into Texas after this. It'll be monitored for mid to late next week, but at this time development chances appear to be very low.


The remnants of east pacific Cristina with some tropical storm warnings up along Guatemala and El Salvador now:

The 2026 Atlantic Hurricane Season Begins Today
Posted: 06:43 AM 01 June 2026 | 2 Comments | Add Comment | Newest: 08:24 PM 02-Jun EDT
This year is expected to be lower than average because of the el nino effect. This is basically a periodic event in the Pacific ocean that warms up temperatures there in the eastern Pacific, which tends to lower pressure there, and force trade winds to be stronger over the Atlantic, as well as the mid Atlantic back feed, which causes windshear and more stability in the atmosphere in general in the Atlantic, which dampens the hurricane season. However, it does not prevent it, some notable storms like hurricane Andrew happened in an El Nino year. So it's important to watch. It does favor storms doing odd tracks and patterns where it typically won't form as far out, for those that form.
In the near term although there is some moisture, there's nothing organized in the Atlantic that looks like it could develop in the next week or two. But the areas typically to watch this time of year are off the southeast coast and Gulf. Have a plan in place if you live in an evacuation area, and get be prepared now, not when a storm is bearing down on you.
Another year here 31st year for flhurricane.com. With some new features like the hurricane radar page on the left, focusing on Atlantic coastal hurricane radars (and Hawaii). We've also made it easier to share graphics like models, satellites and radar in the posts, just upload or even copy paste images into the forums this year, and crop/resize them right on the site.
Names for this year:
| Arthur | Hanna | Omar |
| Bertha | Isaias | Paulette |
| Cristobal | Josephine | Rene |
| Dolly | Kyle |
Sally |
| Edouard | Leah |
Teddy |
| Fay | Marco | Vicky |
| Gonzalo | Nana | Wilfred |
The National Hurricane center is the official source for advisories, warnings, and more, use https://nhc.noaa.gov for the best information. floridadisaster.org for emergency information in Florida. And local media (Tv, radio, papers, etc) for the best information for your particular area if the need arises.
Flhurricane stays away from hype and engagement farming, we do have social media on X and facebook, that we update when necessary. Posting long range modeling runs without context on the main site/socials is something we actively avoid since this we think is generally unhelpful and just causes confusion to highlight them. However, it doesn't mean they are not discussed, for those interested it can be found on the forecast lounge here on flhurricane.com.
There's nothing for the first week in the Atlantic, and over the next two weeks the most likely place to see development is not in the Atlantic, but in the east Pacific.
