Tropical Storm Isaac Forecast Discussion Number 18
2024-09-30 10:35:53| National Hurricane Center (Atlantic)
Issued at 900 AM GMT Mon Sep 30 2024 000 WTNT45 KNHC 300835 TCDAT5 Tropical Storm Isaac Discussion Number 18 NWS National Hurricane Center Miami FL AL102024 900 AM GMT Mon Sep 30 2024 Isaac continues to show signs of transitioning into an extratropical cyclone. The central convection has mostly dissipated, and the system is taking on more of a frontal appearance, with a zonally-oriented cloud and rain shield over the cyclone's northern semicircle. The current intensity is kept at 55 kt in accordance with a Dvorak estimate from TAFB, although this is somewhat uncertain since Isaac no longer appears to be a true tropical cyclone. The cyclone continues to move east-northeastward or at about 060/13 kt within a southern branch of the mid-latitude westerlies. Isaac is expected to turn toward the northeast during the next couple of days as it approaches a shortwave ridge just west of the British Isles. The official track forecast has been nudged only slightly eastward in the 2-3 day time frame, towards the latest corrected dynamical model consensus. Isaac is moving over cool waters and should complete its extratropical transition today. The global models suggest that the system will gradually weaken during the next few days as it becomes absorbed within a larger low over the North Atlantic. The official intensity forecast is similar to the previous NHC prediction.
