Tropical Storm Dora Discussion Number 12
NWS National Hurricane Center Miami FL EP042017
300 PM MDT Tue Jun 27 2017
The convection associated with Dora continues to decrease, with the
center now exposed to the west of a small area of deep convection.
Various satellite intensity estimates range from 54-77 kt, while a
recent ASCAT overpass suggested winds of about 45 kt. The initial
intensity is lowered to 55 kt, and it is possible that this is
generous. Dora should continue to rapidly weaken as it moves over
colder sea surface temperatures, and the system is expected to
become a remnant low in 36 h or less. The official intensity
forecast is again in close agreement with the model consensus ICON.
The initial motion is 290/11. A mid-level subtropical ridge to the
north of Dora should maintain the west-northwestward motion, with
some decrease in forward speed, over the next 36-48 h. After that,
a westward or south of westward motion is expected. The official
forecast track is similar to the previous track, but it lies to the
south of the model consensus between 24-48 hours.
