IAN is now a CAT 2 hurricane with sustained winds of 100 mph, and the following was available from the NHC 8:00 p.m. intermediate advisory:
8:00 PM EDT Mon Sep 26
Location: 20.8°N 83.3°W
Moving: NNW at 13 mph
Min pressure: 965 mb / 28.50 in
Max sustained: 100 mph
Satellite loop imagery indicated earlier that IAN looked a little degraded. However, in the lat few frames in the loop, it appears a counter-clockwise wobble occurred, and it appears there has been a center reformation slightly west, with a burst of convection noted. Based on this, and a drop in barometric pressure from 972 mb, down to 965 mb in a 3 hour period, I believe IAN will begin continued strengthening, and I am still calling for more rapid intensification during the next 24 hours. You’ll note in the water vapor loop that will be posted below, there is now plenty of moisture at the mid level.
GOES 16 SATELLITE LOOP
I believe one reason for the less organized appearance may be that the radial shear pattern that was directly overhead of IAN, has been displaced south of the center, allowing for some slight shear to affect the storm, along with a slight degradation of the upper level outflow pattern. In order for RI to continue, these 2 features need to be pretty well aligned over the center of the hurricane.
CIMSS WIND SHEAR AND UPPER LEVEL WINDS
Though this has occurred, analysis again of the ECMWF and GFS models still indicate the same improving parameters from yesterday evenings forecast in both moisture and the upper pattern. Based on this, and the still extremely high OHC in the path of IAN, I have to once again agree with the NHC intensity forecast, and that IAN will briefly attain CAT 4 status.
NHC INTENSITY FORECAST
INIT 26/2100Z 20.3N 83.2W 85 KT 100 MPH
12H 27/0600Z 21.7N 83.8W 105 KT 120 MPH
24H 27/1800Z 23.6N 84.0W 115 KT 130 MPH
36H 28/0600Z 25.3N 83.9W 120 KT 140 MPH
48H 28/1800Z 26.7N 83.5W 115 KT 130 MPH
60H 29/0600Z 27.5N 83.2W 100 KT 115 MPH
72H 29/1800Z 28.1N 82.9W 75 KT 85 MPH
96H 30/1800Z 30.1N 82.3W 45 KT 50 MPH…INLAND
120H 01/1800Z 33.5N 82.0W 25 KT 30 MPH…INLAND
In about 36 hours, wind shear is forecast to increase to a little over 20 kts, with the shear pattern beginning to become more zonal, with the upper level outflow pattern diminishing as well. The hurricane is forecast to begin weakening as it approaches the Florida coast from CAT 3 to CAT 2. Storm surge is forecast along the west coast of Florida, and is represented in the following graphics. The surge values could be closer to the CAT 3 graphic, as although the storm should be weakening, it takes the surge more time to diminish, so the experience could be CAT 3 storm surge. This is based on current forecast track and forecast intensity. Example was KATRINA. She was a CAT 5, and weakened to CAT 3 before landfall, however MS. still received the surge of a CAT 5 hurricane.
IAN STORM SURGE MEAN TIDE
IAN is currently moving toward the NNW, and based on forecast steering maps, should begin more of a northward turn as it nears the western tip of Cuba.
NHC TRACKING MAP (LINKED)
I am a little perplexed this evening, as current layer mean steering indicates the current flow could send IAN more toward the east earlier, as the trof seems extremely sharp. However, water vapor loop imagery in the mid level which represents approx. 500 mb, indicates the current trof creating the weakness is much flatter in nature, and is more inline with the global models geopotential height forecast. Based on my analysis of forecast steering maps, current track guidance modeling, and the 500 mb geopotential height forecast, I still at the moment have to go with the NHC forecast track, which brings the hurricane over my area in the Tampa Bay area. Another reason for my decision is that, the ECMWF has not budged from its forecast track…for 3 days, and the GFS has come more toward the ECMWF. Guidance indicates the more accurate track models come over the Tampa Bay area, along with the ECMWF. I will monitor this however, for any significant changes in the track motion. Again, conditions can change quickly, but the current analysis indicates really no major change in track at the moment for the next 12 hours.

WATCHES AND WARNINGS
WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Cuban provinces of Isla de Juventud, Pinar del Rio, and Artemisa * Englewood to the Anclote River, including Tampa Bay * Dry Tortugas A Storm Surge Warning is in effect for... * Anclote River southward to Flamingo * Tampa Bay A Tropical Storm Warning is in effect for... * Cuban provinces of La Habana, Mayabeque, and Matanzas * Lower Florida Keys from Seven Mile Bridge westward to Key West * Flamingo to Englewood A Storm Surge Watch is in effect for... * Florida Keys from the Card Sound Bridge westward to Key West * Dry Tortugas * Florida Bay * Aucilla River to Anclote River * Altamaha Sound to Flagler/Volusia County Line * Saint Johns River A Hurricane Watch is in effect for... * North of Anclote River to the Suwannee River * Bonita Beach to Englewood A Tropical Storm Watch is in effect for... * Florida Keys from Seven Mile Bridge to the Channel 5 Bridge * Lake Okeechobee * North of the Suwannee River to Indian Pass * Jupiter Inlet to Altamaha Sound A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests in central Cuba, the remainder of the Florida Keys, and the Florida peninsula should monitor the progress of Ian. For storm information specific to your area, please monitor products issued by your national meteorological service.
HAZARDS AFFECTING LAND ---------------------- Key messages for Ian can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml. STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... * Anclote River to Middle of Longboat Key, FL including Tampa Bay...5-10 ft * Suwannee River to Anclote River...5-8 ft * Middle of Longboat Key, FL to Englewood, FL...5-8 ft * Englewood, FL to Bonita Beach, FL including Charlotte Harbor... 4-7 ft * Bonita Beach, FL to East Cape Sable, FL...3-5 ft * Flagler/Volusia County Line, FL to Altamaha Sound including St. Johns River...2-4 ft * East Cape Sable, FL to Card Sound Bridge, FL including Florida Bay...2-4 ft * Aucilla River to Suwannee River...2-4 ft * Florida Keys including the Dry Tortugas...2-4 ft * Indian Pass, FL to Aucilla River...1-3 ft The deepest water will occur along the immediate coast near and to the right of the center, where the surge will be accompanied by large waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. Storm surge could raise water levels by as much as 9 to 14 feet above normal tide levels along the coast of western Cuba in areas of onshore winds in the hurricane warning area tonight and early Tuesday. WIND: Hurricane conditions are expected within the warning area in Cuba tonight. Destructive winds are possible where the core of Ian moves across western Cuba. Tropical storm conditions are expected within the tropical storm warning area in Cuba tonight and Tuesday. Hurricane conditions are expected along the west coast of Florida within the Hurricane Warning area on Wednesday, with tropical storm conditions possibly beginning by Tuesday night. Tropical storm conditions are expected in the warning area by Tuesday evening. Hurricane conditions are possible in the watch area beginning on Wednesday, and tropical storm conditions are possible in the watch area on Wednesday into early Thursday. Tropical storm conditions are expected in the warning area in the lower Florida Keys and are possible in the watch area in the middle Florida Keys on Tuesday. RAINFALL: Ian is expected to produce the following rainfall through Thursday: * Western Cuba: 6 to 10 inches, with local maxima up to 16 inches. These rains may produce flash flooding and mudslides in areas of higher terrain over western Cuba. * Florida Keys: 4 to 6 inches, with local maxima up to 8 inches. * Coastal Southwest and Southeast Florida: 4 to 6 inches with local maxima up to 10 inches. * Central West Florida: 6 to 12 inches, with local maxima up to 20 inches. * Northeast Florida: 6 to 10 inches, with local maxima up to 12 inches. * Remainder of the Central Florida Peninsula: 4 to 8 inches. Heavy rainfall is expected to affect the Southeast U.S. Friday and Saturday. Widespread considerable flash and urban flooding, and prolonged significant river flooding impacts are likely mid-to-late week across central and northern Florida, southern Georgia, and coastal South Carolina. Flash and urban flooding impacts are also possible with rainfall across the Florida Keys and the Florida peninsula through mid week. Limited flooding impacts and rises on area streams and rivers are also possible over portions of the Southeast mid-to-late week. TORNADOES: A few tornadoes are possible late tonight and Tuesday across the Florida Keys and the southern/central Florida Peninsula. SURF: Swells generated by Ian are affecting Jamaica and the Cayman Islands. Swells will spread northwestward to the southwestern coast of Cuba and the coasts of Honduras, Belize, and the Yucatan Peninsula of Mexico tonight. Swells are expected to begin affecting the Florida Keys Tuesday and spread northward along the west coast of Florida through Wednesday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
