...UPDATE...WEDNESDAY SEPTEMBER 28 2022 10:43 PM EDT...
To the left is a colorized infrared satellite image of Hurricane Ian making landfall over the southwestern part of the Florida peninsula earlier this afternoon. The center and right images are Doppler radar of Hurricane Ian taken at various times after landfall (radar imagery credit goes to Weather For You... https://www.weatherforyou.com/maps/punta+gorda-fl-interactive/26.929/-82.046):
The eye of powerful category 4 Hurricane Ian made landfall in southwestern Florida in the vicinity of Port Charlotte and Punta Gorda at 3:10 PM EDT earlier this afternoon... only weakening just slightly to 150 mph maximum sustained winds from its 155 mph peak. The central pressure was estimated to climb from its 937 mb minimum to a 940 mb minimum at landfall time. Based on initial media reports... it appears devastating wind and coastal storm surge has badly damaged areas in the vicinity of Punta Gorda... Port Charlotte... Fort Myers... and Naples. Further north in west-central Florida (Sarasota... Tampa... Clearwater Beach)... the eye and associated core of strong hurricane winds wobbled more eastward in track and missed the area just to the south. Since landfall... Ian has steadily weakened to a category 2 hurricane with 100 mph maximum sustained winds as of 10 PM EDT while the center continues moving slowly northeast into the central Florida peninsula. Over the next hours... expect inland hurricane wind damage over central Florida to the south of Orlando and north of Lake Okeechobee (recent observations at Sebring Florida suggest hurricane-force winds have arrived here). I currently expect the hurricane force winds to reach as far east as areas just inland of east-central Florida (just inland... or west of... Melbourne... Cape Canaveral... Daytona Beach) before the core of hurricane force winds dissipates. Due to some southwesterly wind shear and ingestion of cooler drier air associated with the large-scale upper troughing over the eastern US and western Gulf of Mexico... Ian's southern thunderstorm activity has eroded away. Meanwhile central and northern parts of the Florida peninsula will remain covered in tropical storm force winds with some damage potential and heavy rainfall with flash flooding potential over the next several hours (if encountering a water-covered roadway... do not drive into it). Coastal surf over the next several hours will gradually decrease over the west coast of the Florida peninsula... and increase across the east coast. The tornadic east side of Ian has moved offshore of Florida's east coast... and the tornado threat appears to have subsided. The Florida panhandle meanwhile has escaped much of Ian's impacts as the hurricane has turned more east and less north in track since this past afternoon. For forecast impacts expected over the next few days over Georgia... the Carolinas... and eastern Tennessee... refer to the update below from 9:20 AM EDT. My next full update on Ian and the rest of the Atlantic tropics will be released by early Thursday morning.
The following are wind reports at National Weather Service stations across the Florida peninsula listed in mph. Due to the number of wind reports listed below... I have organized them by calling out which region of the Florida peninsula the weather station is located (southeast... northeast... etc). The weather station outages currently in progress along southwestern coastal Florida indicate the ferocity this hurricane had at landfall. Note the Punta Gorda weather station held on long enough to register a severe 123 mph gust before its outage:

Blend of infrared and true-color visible satellite as the sun rises over Hurricane Ian during its intensification from a category 3 to top-end category 4... image taken at 1150Z:
Frustrating-to-forecast Major Hurricane Ian has left us speechless this morning. After completion of its eyewall replacement cycle... it is now apparent the hurricane remains in a favorable upper-level wind setup where the northern outflow of the hurricane is boosted by the upper southwesterly flow ongoing out ahead of an upper trough over the eastern United States... instead of this upper flow shearing the hurricane. At 5 AM EDT... aircraft reconnaissance found Ian's surface pressure abruptly fell to 942 mb with winds in the new eyewall of Ian reaching 140 mph maximum sustained. At 6:35 AM EDT the situation has escalated in dramatic fashion with Ian knocking on the door of category 5... as Ian's maximum sustained winds were now clocked by aircraft reconnaissance to be 155 mph. The NHC reported at 7 AM EDT the central surface pressure of Ian had fallen to 937 mb. The situation is made worse as a blocking surface ridge setting up north of the powerful hurricane is making it slow down as the eye nears the west coast of Florida... in the Fort Myers to Port Charlotte region. It could very well be that we do not see enough shear to weaken the hurricane before it makes landfall... and we are faced with the stunning likelihood of a category 4 or 5 hurricane slowing to a crawl next to the Florida west coast:
(1) Along and south of the eye where the wind will most effectively push water toward the shore... coastal storm surge flooding is expected to be potentially catastrophic from the Port Charlotte to Naples region. The storm surge could be long-lasting as Ian slows to a crawl... listen to the advice of your local officials and local news media to evacuate in the face of updated storm surge forecasts if it is safe to evacuate to higher ground now.
(2) In close-proximity to the eye... there is a possibility of long-lasting highly-damaging wind from Fort Myers... across the Port Charlotte/Punta Gorda area... to perhaps as far north as Sarasota if the eye wobbles more toward the north. If in this region... get ready now to shelter in an interior room in the lowest-level of your building and be prepared to hunker there for an extended period of time. Have a battery-powered radio or device to listen for updates on the storm's current situation.
Regarding impacts to land areas:
(1) Coastal surf across western Cuba will continue to gradually improve today as Ian slowly lifts northward and away.
(2) The Florida Keys are being buffeted by tropical storm force conditions (wind and coastal storm surge) on the southeast side of Ian. Expect weather conditions to only gradually improve today as Ian slows down its forward speed.
(3) For the Florida peninsula... the east side of Ian has overspread the area. The expected slow down in the forward speed will subject the peninsula to prolonged impacts such as high rainfall totals creating a risk of major flash flooding... do not drive your car into a water-covered roadway if you encounter one. Much of the west coast of the Florida peninsula will see increasing wind and coastal surf over the next several hours... with a potentially long period of catastrophic storm surge and wind expected from the Naples to Sarasota region... see above statements for more information on this and what to do now. The latest shift in the forecast track means the east side of the peninsula will also see tropical storm force winds with some damage potential... as well as more coastal surf. The east side of Ian has and will continue to be at risk of producing tornadoes due to vertical wind shear between surface southerly flow on the east side of the storm and upper southwesterly flow overspreading Ian... have a way to watch or listen to local media with live coverage to know if you are under a tornado warning... and be prepared to quickly shelter in the lowest-level and interior-most location of your building. The tornado risk looks to overspread southern and central parts of the Florida peninsula... with the latest shift in the forecast track making it harder for Ian to lift its tornadic east side into the northern parts of the peninsula. Preparations across the peninsula should have been completed by now as severe weather has already moved into the area... unless local officials and local news media tell you it is safe to evacuate to higher ground now in the face of updated coastal storm surge forecasts.
(4) For the Florida panhandle... the latest shift in the storm track still will allow for coastal surf for the eastern half of the panhandle. The far eastern panhandle may also see high rainfall totals and flooding as Ian slows its forward speed.
(5) The risk for heavy rainfall and flooding and tropical storm force wind has reduced for southwestern Georgia... however has increased for southeastern Georgia. Coastal Georgia is also at increased risk for coastal surf. Timing of impacts for southeastern Georgia is late Thursday through early Saturday. Prepare now... and finish preparing by late tonight.
(6) Coastal South Carolina and coastal southern North Carolina can expect coastal surf to develop late Thursday through early Saturday. Stronger coastal surf... along with tropical storm force winds with some damage potential... is now expected across southern South Carolina where preparations should now be underway. Finish preparing by late tonight.
(7) Some heavy rainfall with isolated flash flooding potential is possible across northern Georgia... the Carolinas... and eastern Tennessee by Sunday if the current forecast holds.
