Issued at 500 PM AST Thu Oct 31 2019 000 WTNT44 KNHC 312032 TCDAT4 Subtropical Storm Rebekah Discussion Number 5 NWS National Hurricane Center Miami FL AL192019 500 PM AST Thu Oct 31 2019 Rebekah continues to have a small band of moderate-to-deep convection around the center, although the overall cloud pattern is becoming stretched from northeast to southwest. The initial wind speed is kept at 40 kt. All of the models keep stretching Rebekah out overnight and show it degenerating into a trough within 24 h while it moves eastward. A convergent environment and the cyclone's movement over cool waters are expected to offset any cooling aloft which would promote convection. Since Rebekah is not expected to be a tropical or subtropical cyclone near the Azores, hazard information can be found in regular products issued by the Portuguese Institute for the Sea and Atmosphere (IPMA) for those islands at https://www.ipma.pt/pt/index.html.
