Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0234 PM CDT Thu Sep 26 2024 Valid 262000Z - 271200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS COASTAL AREAS OF NORTHEAST FLORIDA...GEORGIA...SOUTH CAROLINA...AND FAR SOUTHERN NORTH CAROLINA... ...SUMMARY... Several tornadoes remain possible this afternoon into tonight across the coastal Southeast in association with Hurricane Helene. The greatest threat is expected across parts of Florida into southeast Georgia, the Midlands and Low Country of South Carolina, and southern North Carolina. ...20Z... The Day 1 Convective Outlook remains on track. Multiple rainbands with embedded low-topped, rotating storms continue to progress across the FL Panhandle into central GA and SC. As the center of Hurricane Helene approaches the FL coastline later this evening, the vertical wind (and associated shear) profiles should increase further across northern FL into the Carolinas. Large, curved hodographs will support tornado potential with any embedded supercell structures that can develop amid surface-based buoyancy. The latest CAM guidance depicts an arc of low-topped supercells to the northeast of Helene's center moving across central and eastern SC between 06-12Z, when tornado potential will be maximized. If enough surface-based buoyancy can advect inland, a strong tornado could develop closer to the SC coastline. ..Squitieri.. 09/26/2024 .PREV DISCUSSION... /ISSUED 1127 AM CDT Thu Sep 26 2024/ ...Florida/Georgia into the Carolinas... Hurricane Helene is currently centered about 200 miles southwest of SRQ. This system is characterized by a very broad/expansive wind field, with the VAD profiles at JAX and CLX showing 50 and 35 kt at 2 km, respectively. Stronger low-level winds are already in place across FL. Rotation has been noted in cells both off the central FL Panhandle south of TLH as well as from coastal GA into the SC Low Country. The general trend of rotation within the deeper, more cellular convection is expected to continue throughout the day into the evening across the entire region, with some chance for an increased frequency of rotating cells given the strengthening wind profiles. Best overlap between modest buoyancy and veering low-level wind profiles is still expected to occur from southeast GA northward into coastal SC and far southern NC (i.e. ILM vicinity). For much of this region, the higher dewpoints currently remain offshore, but additional advection inland is anticipated as the system moves northward. This additional low-level moisture should increase buoyancy slightly, which is expected to result in a relatively higher tornado threat. This relatively higher tornado risk is expected from 04Z to 18Z Friday, which bridges the Day 1 and Day 2 periods. As such, additional information regarding the tornado risk for this area can be found in the Day 2 Convective Outlook. Read more

WW 685 TORNADO FL GA CW 261445Z - 270200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 685 NWS Storm Prediction Center Norman OK 1045 AM EDT Thu Sep 26 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northern Florida Southern Georgia Coastal Waters * Effective this Thursday morning and evening from 1045 AM until 1000 PM EDT. * Primary threats include... Several tornadoes likely SUMMARY...Rainbands associated with Hurricane Helene will continue to move through this area throughout the day. Wind fields will strengthen as the hurricane continues northward, with low-level winds becoming increasingly favorable for tornadoes. These conditions will result in a long-duration risk for tornadoes across northern Florida and southern Georgia. The tornado watch area is approximately along and 60 statute miles north and south of a line from 40 miles west northwest of Tallahassee FL to 60 miles north northeast of Gainesville FL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && OTHER WATCH INFORMATION...CONTINUE...WW 683...WW 684... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 0.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 16035. ...Mosier Read more
