EX-TROPICAL STORM MALOU 2021
Last Modified: 15:00 October 29, 2021, UTC
Rapid weakening is beginning as Malou merges with the nearby frontal boundary and translates northeastward over cooler waters, which will also result in a quick transition to an extratropical cyclone during the next 12 to 24 hours.
Dynamical model guidance agrees that the vortex will lose vertical coherence by that time as it becomes baroclinic in nature. The JTWC forecast terminates at 24 hours as Malou becomes a gale-force extratropical cyclone well east of Hokkaido.
Model guidance remains tightly clustered during the forecast period. The JTWC track forecast is close to the multimodel consensus, as is the intensity forecast.
Maximum significant wave height is 11 meters (36 feet).
