Post-Tropical Cyclone Kyle Forecast Discussion Number 7
2020-08-16 10:47:32| National Hurricane Center (Atlantic)
Issued at 500 AM AST Sun Aug 16 2020 000 WTNT42 KNHC 160847 TCDAT2 Post-Tropical Cyclone Kyle Discussion Number 7 NWS National Hurricane Center Miami FL AL122020 500 AM AST Sun Aug 16 2020 Shortwave infrared satellite imagery and earlier ASCAT data indicate that Kyle's circulation has become very elongated, and the center has become ill defined. Model analyses and satellite imagery also suggest that the low is now attached to a prominent warm/stationary front to its east and a weaker trailing cold front to its southwest. Therefore, Kyle has become an extratropical low, and its maximum winds are estimated to be 35 kt based on the earlier ASCAT data. Global models indicate that Kyle's winds should continue to decrease over the next couple of days, with the system dissipating or becoming absorbed by another area of low pressure in about 48 hours. The initial motion is eastward, or 080/17 kt. Since Kyle is embedded in zonal mid-latitude flow, this general heading and speed are expected to continue during the next day or two until the cyclone dissipates.

Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Little change in strength is forecast before the system dissipates by Monday night. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 1003 mb (29.62 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.
