Five Storms at Once: Tonight's Wild Tropical Weather Map
Three hurricanes, a nor'easter, and a full moon are colliding this weekend. Here's what Hurricane Polo, Nolo, and coastal king tides mean for your plans.
Five Storms Spinning at Once: What Tonight's Wild Tropical Map Means for You
Alright folks, if you glanced at a tropical weather map today and thought "wait, is that right?" you're not losing it. As of tonight there are five separate tropical systems on the board across two oceans. Three hurricanes. One post-tropical mess. One depression just kind of wandering the open Atlantic. Weather nerds have been passing screenshots around all afternoon, and for once, the chaos is real.
Here's the rundown, because context matters more than the headline count.
The Big One: Hurricane Polo
Polo is a Category 4 hurricane sitting about 335 miles southwest of Cabo San Lucas, packing 144 mph winds and a central pressure of 938 millibars. That's a serious storm. Hurricane hunters are flying it right now, and the discussion out of NHC mentions Polo may be going through an eyewall replacement cycle, which is the storm's internal plumbing reshuffling itself. It can cause temporary weakening even while the storm stays dangerous.
Polo is forecast to approach Baja California Sur by Monday, with places like Loreto and Guaymas under a "prepare" threat level in current impact modeling. If you've got family or property down that way, Monday is your day to have a plan finished, not started.
Nolo, Grinding Away at Hawaii
While Polo gets the headlines, Hurricane Nolo has been the quieter, meaner story. It's a Category 1 sitting south of the Big Island, and it's been struggling against dry air intrusions for days according to the forecast discussion. The wind speed number, 92 mph, undersells the real threat here. Storm total rainfall of 10 to 20 inches, with isolated spots near 25, is producing what NWS is calling life-threatening flooding and mudslides across Hawaii Island and eastern Maui. This is the kind of storm where the flood danger outlasts the wind danger by days.
The Other Three
- Odalys is a Category 1 well offshore, quickly weakening, no coastal threat expected.
- Post-Tropical Cyclone Gonzalo just got its final advisory near Cabo Verde. Done and done.
- Tropical Depression Fay is out in the middle of the Atlantic, moving at a crawl, headed nowhere near land any time soon.
Five systems is a lot, but only two of them, Polo and Nolo, are actually threatening people right now. That's the number that matters.
Back Home, the Moon Is Doing Its Own Damage
Here's the part that actually affects your weekend if you live anywhere from the Jersey Shore to Cape Cod. There's a nor'easter parked off the coast, spinning at 986 millibars, and it is going nowhere fast. WPC has a Slight Risk of excessive rainfall out for the coastal Northeast today and tomorrow, with another 1 to 2.5 inches on top of what's already fallen.
Normally that's a rain story. But this storm is arriving during a full moon, and that combination is the real headline. Full moons bring higher astronomical tides on their own. Stack a slow-spinning coastal storm with onshore wind on top of that, and you get what folks call a king tide: water pushing well past the normal high-tide line, flooding streets that are usually dry. NWS offices from Philadelphia to Boston have flagged this exact setup, with 45 to 65 mph gusts adding to the surge risk along Cape Cod, Long Island Sound, and the Chesapeake.
This isn't a new story for this stretch of coast this month either. Back on September 13th, this same general corridor, from Philly through Stamford to New Haven, took 3 to 5 inches of rain in just a few hours and flooded streets, stranded cars, and forced water rescues. This week's version is slower and less explosive, but the water keeps showing up in the same places because the geography doesn't change, even when the storm does.
If you're at All Things Go Music Festival in Columbia, Maryland this weekend, you're inland enough to dodge the worst of the coastal flooding, but you're still under the outer edge of this system's moisture. Expect lingering clouds, on-and-off showers, and gusty wind, not a washout, but bring a poncho and don't be shocked if the grounds get soggy underfoot. If you were out at Oceans Calling in Ocean City earlier this weekend, you already know. That coastline got the early bands of this same storm.
And Don't Sleep on the Plains
One more piece worth knowing about if you're anywhere near western Oklahoma or northwest Texas tonight. SPC has a Marginal Risk out for places like Wichita Falls, Lawton, Enid, Altus, and Alva for isolated hail and strong outflow winds this evening. Nothing widespread, just enough that if you're driving back roads through that stretch after dark, don't be surprised by a pop-up storm with a gusty punch behind it.
The Takeaway
Hurricane season doesn't pause for festival season, and the ocean doesn't care what's on your calendar. Tonight the tropics are doing five things at once, a slow coastal storm is teaming up with a full moon to flood streets that flooded two weeks ago, and somewhere in the southern Plains a stray storm cell is minding its own business. None of that has to ruin your weekend. It just means you check the forecast for wherever you're actually standing, not the forecast for wherever the internet is looking.
