Preliminary details from NWS Mobile, Alabama regarding Hurricane Isaias.

Brian LaMarre @blamarre.bsky.social · 10/10/2026

Throughout the sequence, the eventual landfall location remained inside the office forecast track area, or “cone” - initially along its right-hand side. This is an important reminder: the forecast cone represents a probability of where the “center” of the storm could make landfall.

Brian LaMarre @blamarre.bsky.social · 10/10/2026

This animation follows every National Hurricane Center (NHC) advisory for #Isaias from 4 PM CT Tue, Oct 6, through landfall near Destin, FL, Fri eve at 8:30 PM CT, and the system’s transition to post-tropical over southern Alabama. Science and innovation continue to lead the way.

🧵 2/2 As shown radar imagery, the eye-wall can be seen moving toward the FL panhandle with bands of flooding rain and thunderstorms seen extending far from the center. Not seen in the radar imagery was the powerful storm surge flooding as Gulf waters pushed inland along the coastline.

Hurricane Isaias radar animation from 1:36 PM ET Friday October 9 through 7:34 AM ET Saturday October 10, 2026. Hurricane Isaias made landfall near Destin, Florida at 8:30 PM ET Friday October 9th as a category 2 hurricane with maximum sustained winds at 90 knots (105 mph) with higher gusts. 🧵 1/2

Brian LaMarre @blamarre.bsky.social · 09/10/2026

If you have not taken precautions already, do so early today and listen to local NWS offices, emergency management and trusted media sources across the MS-AL coastline and FL Panhandle with the area from Mobile to Pensacola to Destin in highest probability for intense wind and deadly storm surge.

Brian LaMarre @blamarre.bsky.social · 09/10/2026

It is always a gut-wrenching feeling seeing these storms intensify leading up to landfall where many people will be impacted. 1/2

Thanks to meteorologist Ari Sarsalari with FOX #Weather for the interview tonight discussing #hurricane science and history and the impacts expected from Hurricane #Isaias.

Brian LaMarre @blamarre.bsky.social · 07/10/2026

Edit: “…as it may become the first hurricane to form so late in the season in the Atlantic Basin…”

Brian LaMarre @blamarre.bsky.social · 07/10/2026

Excellent interview, Dr. Tracy Fanara, with Kiyana Lewis from Fox Weather discussing developing #hurricane #isaias and the expected impacts across the area - both inside and outside the “cone” of uncertainty. @inspectorplanet.bsky.social

000

Brian LaMarre @blamarre.bsky.social · 07/10/2026

Note how the impacts extend outside of the historical “cone”. This is common and usually surprises people when their location is not in the “cone” but may receive storm surge / coastal flooding, torrential inland rain and tornadoes. 🧵4/4

010

Brian LaMarre @blamarre.bsky.social · 07/10/2026

The impressive outflow and tightening circulation can be seen in the satellite images, However, the impacts are what matter most for people, as shown by the Hurricane Threats and Impacts (HTI) from the National Weather Service. 🧵3/4

Brian LaMarre @blamarre.bsky.social · 07/10/2026

October 8, 1905 is currently the latest date on record for the first hurricane formation. The NHC forecast has Isaias strengthening tonight and becoming a hurricane tomorrow, October 8, 2026. 🧵2/4

Brian LaMarre @blamarre.bsky.social · 07/10/2026

Tropical Storm #Isaias will be one for the record books, as it may become the latest #hurricane formation in the Atlantic Basin (including the Gulf and Caribbean). The record? 🧵1/4

Brian LaMarre @blamarre.bsky.social · 06/10/2026

2/2 Environmental conditions are supportive of an additional surge of moisture across this front into the north-central Gulf later this week with numerical weather prediction ensemble data showing consistency with some form of tropical cyclone development originating from the Bay of Campeche.

000

Brian LaMarre @blamarre.bsky.social · 06/10/2026

1/2 Can you spot the front on this Tuesday afternoon? The wet weather pattern continues to take shape, regardless of tropical cyclone development later this week, as deep moisture streams across Florida and Gulf coastal states.

Weather #History: 56 years ago today! On October 3, 1970, NOAA was created within the U.S. Department of Commerce and a few days later, on October 9, 1970 the U.S. #Weather Bureau was renamed to the U.S. National Weather Service.

Brian LaMarre @blamarre.bsky.social · 28/09/2026

Not to be left out, tropical storm #rachel is located about 225 miles off the coast of #acapulco and will strengthen into a #hurricane on Wednesday as it tracks toward Baja peninsula.

011

Brian LaMarre @blamarre.bsky.social · 28/09/2026

Meanwhile, Hurricane #polo remains a formidable tropical cyclone, located about 80 miles from Cabo San Lazaro off the coast of the Baja and will heavily contribute to rain and flood potential over portions of #Arizona and #NewMexico this week and into west #Texas.

Brian LaMarre @blamarre.bsky.social · 28/09/2026

Ready for more "visible" #weather satellite images? The #noreaster continues to overstay its welcome across the NE U.S., apparently waiting for better views of the Fall #foliage, as coastal wind and flooding impacts continue. The good news is it will be departing tomorrow.

When you’re looking at what is thought to be a seagull resting in an open parking spot in South Tampa, you zoom in from afar with your iPhone camera and…well, you realize it is not a resting seagull.

The center of low pressure associated with the #noreaster continued to be exposed with an isolated burst of convection on the northern edge of the central vortex this Saturday afternoon, as seen nicely in this satellite animation. Significant impacts continue ahead of this storm.

Brian LaMarre @blamarre.bsky.social · 26/09/2026

Dry air and subsidence wrapping around the western quadrant of the #noreaster with its exposed center of circulation located south of New England in this impressive visible satellite image from 11:36 AM ET this Saturday morning.

020

Brian LaMarre @blamarre.bsky.social · 26/09/2026

In the water vapor and infrared images, note the drier air enveloping much of the north-south axis of the broader circulation with tight moisture gradients to the east and west of the exposed center.

Brian LaMarre @blamarre.bsky.social · 26/09/2026

First “visible” satellite image of the #noreaster this Saturday morning east and offshore Maryland with gale force wind gusts, powerful waves, coastal flooding and beach erosion continuing along portions of the northeast U.S.

Brian LaMarre @blamarre.bsky.social · 25/09/2026

Meanwhile, offshore VA/NC, a developing #noreaster can be seen with its center visible as an open vortex despite producing significant waves and swells causing beach erosion along portions of the U.S. eastern seaboard. The Nor'easter is forecast to track toward the northeast U.S. this weekend.

Brian LaMarre @blamarre.bsky.social · 25/09/2026

Incredible images this Friday morning, including sunrise dividing the powerful eye of Hurricane #Polo over the eastern Pacific with 160 mph maximum sustained wind. Polo is forecast to track west and northwest this weekend and curve toward Baja and into Mexico early next week.

The normal high/low temps for the Tampa Bay area hover around 90F/75F this time of year and we will be a few degrees below, as dew points in the 60s and 50s filter into the area. Be sure to enjoy it, as normal to slightly above normal temperatures and more moist dew points will return next week!

011

Brian LaMarre @blamarre.bsky.social · 24/09/2026

The menu for us in Florida will include sunny daytime skies and, most notably, the lower dew points (how "muggy" it feels), as illustrated in the rapid ensemble forecast system (REFS) model output for surface dew point and wind speed/direction.

110

Brian LaMarre @blamarre.bsky.social · 24/09/2026

The first taste of the Fall season will be pushing southward into Florida starting tomorrow and lasting through the weekend, as a powerful low pressure system, or "Nor'easter" develops off the Mid Atlantic region and tracks toward New England.

Excellent, Chris. BlueSky has character limits so I’ll post my response from X.

A modeled view from the GFS of 250 mb wind to illustrate the passage of the upper-level low pressure system over Florida.

Brian LaMarre @blamarre.bsky.social · 20/09/2026

For the Skew-T enthusiasts of weather data analysis, the upper-level low pressure system that passed from east to west across FL the last few days, the passage is evident in the wind flow shifts from NE to N on Thu and Fri to SW on Sat and now SE as of this Sun morning.

Brian LaMarre @blamarre.bsky.social · 20/09/2026

The number of lightning fatalities has dropped significantly over the last few decades and it is a direct result of enhanced education and preparedness actions. The curve may soon start moving in the opposite direction given shifts in society to ignore credible science and prevention factors.

Radar animation of the thunderstorm activity that moved across the Tampa Bay area this afternoon.

Brian LaMarre @blamarre.bsky.social · 19/09/2026

Heavy rain occurred across portions of Tampa Bay this afternoon, as outflow boundaries interacted with one another as an upper low pressure system started to push off the Florida west coast. The Tampa International Airport (TPA) measured 1.09 inches of rain in about :50 minutes before 5 PM!

Brian LaMarre @blamarre.bsky.social · 18/09/2026

When an upper-level, cold pocket of air moves toward the Tampa Bay area with surface temperatures near 90F, you need to watch out for… blowing snow … or, errors with folks reporting rain. Thankfully, the observer corrected it in mPING. #weather

If this were March or April, it would be an environment conducive for Florida hail, but the freezing level noted in the 12Z morning balloon data is a bit too high for this current setup. #weather

Brian LaMarre @blamarre.bsky.social · 18/09/2026

Impressive cold pocket -10C air at 500 mb around 18-20k feet in the atmosphere will be rotating over the state today and Saturday. Although the overall storm coverage will be less than we observed over the last few weeks, a couple updrafts will have an extra kick! #weather
