Hurricane Hunters sampling #Ian this evening have found the storm to be strengthening, arguably more than what was expected from this morning's forecasts, w/ SFMR of up to ~ 75 kts (85 mph) in #Ian's NW quadrant. #ncwx#scwx
For the Carolinas, I'm more concerned about wx impacts than I was this morning, esp for the Pee Dee region of SC into east-central NC. The combo of heavy rain leading to saturated ground + wind gusts of 50-60+ mph will favor 🌳 falling onto power lines/power outages
Here's the latest NWS NDFD max wind gust & WPC precip fcsts. Given #Ian's more impressive than expected strengthening today, there's certainly a small chance hurricane-force wind gusts (74+ mph) could sneak as far north as the southern coastal plain of NC.
Hurricane #Ian is starting to undergo extratropical transition tonight on its way to the Carolinas. Notice the big dry slot sneaking in from the SW and frontal boundary extending from #Ian's south into the Bahamas...
Fwiw, one of the simplest methods I use to discern b/t tropical & extratropical cyclones is to locate the subtropical jet & assume everything poleward/north of that is extratropical, while to the south = tropical. #Ian is in the middle rn => "hybrid" warm core/subtropical cyclone
This method checks out here. PV x-sect for #Ian has elements of both tropical & subtropical cyclones atm. Low-mid lvl PV tower overlaid by an outflow high is characteristic of tropical cyclones but the intruding upper trough from the NW is the hallmark of an extratropical cyclone
