Subtropical Storm Rebekah Discussion Number   4
NWS National Hurricane Center Miami FL       AL192019

The storm has lost organization since yesterday with only a skeletal
curved band west and north of the center.  However, ASCAT just came
in with 35-40 kt winds, so the initial wind speed will stay 40 kt.
Weakening is anticipated today as the low moves over cool waters and
into a convergent environment aloft.  All of the guidance shows any
remaining convection dissipating by this evening, so the storm will
likely be in the graveyard in about 12 h. A general eastward track
is forecast until Rebekah decomposes into a trough sometime
tomorrow, at best becoming a wave along an approaching cold front.

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
