Post-Tropical Cyclone Melissa Forecast Discussion Number 13

2019-10-14 16:38:55| National Hurricane Center (Atlantic)

Issued at 1100 AM AST Mon Oct 14 2019 000 WTNT44 KNHC 141438 TCDAT4 Post-Tropical Cyclone Melissa Discussion Number 13 NWS National Hurricane Center Miami FL AL142019 1100 AM AST Mon Oct 14 2019 Melissa has transitioned to an extratropical cyclone. Shallow convection has become displaced greater than 100 n mi from the center, and Melissa's circulation has become embedded within a frontal zone. The inner-core now consists of a swirl of low clouds with a large amount of cool post-frontal stratocumulus wrapping into the northern and western portions of the circulation. A recent ship report just southwest of the center indicated gale-force winds are still occuring in association with Melissa, and 35 kt will be this advisory's initial intensity. The extratropical cyclone is expected to gradually weaken over the next day or so, and dissipate before it reaches the Azores. Melissa is now moving at 080/20 kt and is embedded within mid-latitude westerlies. This general motion is expected to continue until the cyclone dissipates. This is the last advisory on Melissa from the National Hurricane Center. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service...under AWIPS header NFDHSFAT1 and WMO header FZNT01 KWBC.
