Hurricane Kirk Forecast Discussion Number 12
2024-10-02 16:52:26| National Hurricane Center (Atlantic)
Issued at 1100 AM AST Wed Oct 02 2024 000 WTNT42 KNHC 021452 TCDAT2 Hurricane Kirk Discussion Number 12 NWS National Hurricane Center Miami FL AL122024 1100 AM AST Wed Oct 02 2024 Kirk continues to intensify this morning. On geostationary satellite imagery convective bands continue to rotate around the eye seen earlier in microwave imagery, although this feature hasn't shown up yet on visible imagery. The subjective Dvorak estimates were a consensus T4.5/77 kt, and blending these estimates with somewhat lower objective intensity estimates, the intensity has been raised to 75 kt this advisory. Kirk continues moving northwestward, or 305/10 kt. A gradual slowdown at a similar heading is expected over the next day or two as the hurricane remains steered by a subtropical ridge centered to its northeast. At the end of the week, Kirk will find itself between an increasingly eroded ridge to its east, and a digging upper-level trough to its west, and it is likely Kirk will be steered between these features, recurving northward, and then north-northeastward by the end of the forecast period. The latest NHC track forecast is very similar to the prior one, especially over the next several days, but is a little further northwest thereafter, blending the prior track forecast to the consensus aids TCVA and HCCA, though in general the track spread among the track guidance remains relatively low. Kirk appears poised to intensify quite a bit in the short-term now that shear has decreased as the hurricane remains over very warm ocean waters and plenty of deep-layer moisture. These favorable conditions should promote notable strengthening, and the latest NHC intensity forecast now shows Kirk becoming a major hurricane in 24 h, and peaking as a 115 kt Category 4 hurricane in 48 h. Thereafter, southwesterly shear from the upper-level trough to its west could begin to increase, leading to a gradual weakening trend. The latest intensity forecast is a little higher than earlier, owing to somewhat higher intensity guidance aids this cycle, but still remains lower than some of the more bullish guidance (HAFS-B) but is roughly in line with HCCA this cycle. Kirk is also expected to continue growing in size with a larger than average radius of both tropical storm and hurricane-force wind radii as it recurves into the open Atlantic Ocean.

SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...18.0N 43.0W ABOUT 1260 MI...2030 KM W OF THE CABO VERDE ISLANDS ABOUT 1225 MI...1970 KM E OF THE LESSER ANTILLES MAXIMUM SUSTAINED WINDS...85 MPH...140 KM/H PRESENT MOVEMENT...NW OR 305 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...980 MB...28.94 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Hurricane Kirk was located near latitude 18.0 North, longitude 43.0 West. Kirk is moving toward the northwest near 12 mph (19 km/h) and this motion is expected over the next several days with a gradual turn more to the north-northwest by the end of the week. Maximum sustained winds have increased to near 85 mph (140 km/h) with higher gusts. Additional strengthening is forecast, and Kirk is forecast to become a major hurricane tomorrow. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 980 mb (28.94 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Kirk are beginning to spread outward and could affect affect portions of Leeward Islands and Bermuda by this weekend.
