Tesla’s Plan for Hurricane Isaias Has a Megapack Twist

Tesla is telling owners in the path of Hurricane Isaias to charge their cars to 100% at home before the storm hits the U.S. Gulf Coast, and says it’s ready to deploy Megapack-powered mobile Superchargers wherever charging is hit hardest once it passes.

The company’s Tesla Charging account laid out the plan on X Thursday morning in three short points. Owners charging at home should fill up completely, live Supercharger availability is in the car’s touchscreen and the Tesla app, and Tesla’s priority splits in two around landfall.

“Pre-storm, we are focused on uptime of Superchargers,” Tesla Charging wrote. “Post-storm, our focus is on restoration, and we are prepared to deploy mobile Superchargers powered by Megapacks where access to charging is most impacted.”

Isaias had maximum sustained winds near 85 mph as of the National Hurricane Center’s 10 a.m. CDT advisory Thursday, about 380 miles south of the mouth of the Mississippi River. Forecasters expect more strengthening through early Friday and landfall on the northern Gulf Coast late Friday or early Saturday. A Hurricane Warning stretches from Ocean Springs, Mississippi, to the Bay/Gulf County line in the Florida Panhandle, with storm surge of up to 7 feet possible along parts of that coast.

The NHC is telling residents of the Florida Panhandle, southern Alabama and southern Mississippi to “prepare for the possibility of long-duration power outages,” and expects damaging gusts well inland across Alabama and Georgia. Home chargers and Superchargers both depend on that grid, so a car that starts the storm full gives owners the most breathing room if the power stays off for days.

Tesla ran the same playbook during Hurricane Milton in October 2024, when Tesla Charging posted a nearly identical list, and three days after Milton came ashore it said it had deployed Megapack-powered mobile Superchargers at its Brandon, Florida, site. In 2022, Tesla sent owners an in-car message urging a 100% charge as Hurricane Ian closed in on Florida.

Those Megapack trailers have also shown up outside hurricane season, starting with the Los Angeles wildfires in January 2025, when Tesla parked mobile units at its Thousand Oaks, California, Supercharger with up to 16 stalls at 250 kW, free Starlink Wi-Fi for anyone nearby and charging open to all EVs. It sent the same kind of equipment to busy California and Ohio sites ahead of Thanksgiving travel last year.

Tesla’s Isaias post doesn’t name any Supercharger sites it’s watching or say how many mobile units it has staged near the Gulf Coast. It also doesn’t say whether the mobile stalls would be open to non-Tesla EVs this time, as they were in Thousand Oaks, and it drops the line from the Milton post pointing other EV drivers to access types on Tesla’s Find Us map. There’s no mention of free Supercharging in affected areas either, so owners counting on any of that should keep an eye on the Tesla app and the Tesla Charging account after landfall.

Where the trailers end up will depend on where Isaias actually comes ashore and which sites lose power, so the real test of Tesla’s plan starts this weekend, after the wind dies down.
