Griizzcoat Posted September 27 Share Posted September 27 Helene is nothing like Hugo as as far as 64kt wind radii at or near landfall Hugo was 140 mile 64kt wind radii at or near landfall-- and scored a whopping 19.3 on the CMEHI index (https://en.wikipedia.org/wiki/Chicago_Mercantile_Exchange_Hurricane_Index) Looks like Helene had about 50 mile 64kt wind radii at or near landfall -- HURRICANE HELENE FORECAST/ADVISORY NUMBER 15 NWS NATIONAL HURRICANE CENTER MIAMI FL AL092024 0300 UTC FRI SEP 27 2024 HURRICANE CENTER LOCATED NEAR 29.9N 83.9W AT 27/0300Z POSITION ACCURATE WITHIN 15 NM PRESENT MOVEMENT TOWARD THE NORTH-NORTHEAST OR 15 DEGREES AT 21 KT ESTIMATED MINIMUM CENTRAL PRESSURE 938 MB MAX SUSTAINED WINDS 120 KT WITH GUSTS TO 140 KT. 64 KT....... 50NE 50SE 30SW 40NW. Not trying to minimize the impacts and we really have not seen the results of the surge and flooding- but according to the CMEHI index- Helene will score about 11 to 11.5 with a landfall wind speed of 140 and 64 kt wind radii at 50 miles. 2 1 Link to comment Share on other sites More sharing options...

GaWx Posted September 27 Share Posted September 27 After the earlier very high gusts 2 hrs ago that took my power, there had not been a repeat of wind gusts nearly that high until ~3AM, when they returned.

GaWx Posted September 27 Share Posted September 27 From NHC at 4AM: A University of Georgia weather station in Vidalia, Georgia recently reported a wind gust of 77 mph (124 km/h).

NorthHillsWx Posted September 27 Share Posted September 27 That SE quadrant is benefiting from the 30 mph forward motion to keep these strong gusts going. I expect this to continue into the upstate and mountains. Augusta is about to get rocked, fully expect hurricane force gusts there 1 Link to comment Share on other sites More sharing options...
NorthHillsWx Posted September 27 Share Posted September 27 And it does appear to continue wanting to deviate east of track. Could increase wind threat for Charlotte and Greenville down the line if that continues Link to comment Share on other sites More sharing options...
lilj4425 Posted September 27 Share Posted September 27 So much for a northwest turn. This thing is headed right for Greenville-Spartanburg. Link to comment Share on other sites More sharing options...
NorthHillsWx Posted September 27 Share Posted September 27 Still lightning ongoing in remnant eyewall. That tells me this thing is getting some upper level assistance and also that unusually deep convection for being this far inland will be efficient at mixing winds to the surface. Velocities over 90 kts showing on radar emphasize the wind potential this system continues to have. By all accounts, this is going to be one of the most prolific wind storms in the history of Georgia and possibly the upstate and mountains. I can see gusts of 70+ kts continuing into the mountains 1 Link to comment Share on other sites More sharing options...

yoda Posted September 27 Share Posted September 27 No more hourly updates Tropical Storm Helene Discussion Number 16 NWS National Hurricane Center Miami FL AL092024 500 AM EDT Fri Sep 27 2024 The eye of Helene made landfall near Perry, Florida, just after the last advisory was issued. Since then, the center has crossed the Florida Big Bend region and is currently located over east central Georgia. Surface observations have shown steady weakening since landfall, and the maximum winds have decreased to a possibly generous 60 kt. During the last couple of hours, the radar signature of the cyclone has degraded, and based on this the hourly Tropical Cyclone Updates will be discontinued. The initial motion is now northward or 360/26. Helen should turn northwestward later today as it starts to interact with a mid- to upper-level baroclinic low to its northwest. After that, the cyclone should considerably slow its forward motion and make a cyclonic loop as it gets absorbed into the low. The new forecast track follows the general trend of the large-scale dynamical models. Helene should continue to weaken, and simulated satellite imagery suggests it should lose its convection later today, the new intensity forecast calls for the cyclone to weaken and become post-tropical in about 12 h, followed by transition to an extratropical cyclone as it merges with the baroclinic low. The remnant extratropical low is expected to dissipate by 72 h. Although the system will weaken as it moves over land, the fast forward speed of Helene during the next 12 hours or so will result in a far inland penetration of strong winds over parts of the southeastern United States, particularly over northern Georgia, including strong gusts over the higher terrain of the southern Appalachians. Accordingly, a higher-than-normal gust factor is indicated in the official forecast while Helene is inland. KEY MESSAGES: 1. The storm surge along portions of the Florida Big Bend coast and other portions of the west coast of Florida should subside today. 2. Damaging wind gusts will continue to penetrate well inland over portions of Georgia and the Carolinas today, particularly over the higher terrain of the southern Appalachians. Residents in these areas should be prepared for the possibility of long-duration power outages. If you use a generator after the storm, be sure it is placed outside at least 20 feet away from doors, windows, and garages to avoid deadly carbon monoxide poisoning. 3. Catastrophic and life-threatening flash and urban flooding, including numerous significant landslides, is expected across portions of the southern Appalachians through Friday. Considerable to locally catastrophic flash and urban flooding is likely for northwestern and northern Florida and the Southeast through Friday. Widespread significant river flooding is likely, some of which will be major to record breaking.

NorthHillsWx Posted September 27 Share Posted September 27 Augusta is currently sustained 51 gusting to 73. That is one of the more impressive sustained inland wind readings I’ve ever seen from a non elevated site thus far from a tropical systems landfall. There is no doubt devastating tree damage occurring. The core of the hurricane force gusts looks aimed for Greenville to me 1 Link to comment Share on other sites More sharing options...

osfan24 Posted September 27 Share Posted September 27 6 hours ago, eduggs said: We go through this every time with landfalling hurricanes... Where's my 140 mph winds!!?? Due to friction with the ground surface, surface wind speeds are significantly lower over land than over water. So unless someone is literally right on a wind-exposed beach, which is not advisable in a surge scenario, it is very unlikely to record a peak wind speed anywhere close to what would be observed on the open ocean. I always wonder if there is a better way to communicate this to the public in terms of what category or wind speed they say a certain tropical system is as it comes ashore. 1 Link to comment Share on other sites More sharing options...
