At 1100 AM AST (1500 UTC), the center of Post-Tropical Cyclone Rina
was located near latitude 47.0 North, longitude 45.5 West. The
post-tropical cyclone is moving toward the northeast near 40 mph (65
km/h) and a faster northeastward or east-northeastward motion is
expected until dissipation tomorrow.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Little change in strength is forecast before the low dissipates
tomorrow.

Tropical-storm-force winds extend outward up to 275 miles (445 km),
mainly to the east of the center.

The estimated minimum central pressure is 998 mb (29.47 inches).

Post-Tropical Cyclone Rina Discussion Number 14
NWS National Hurricane Center Miami FL AL192017
1100 AM AST Thu Nov 09 2017

Satellite images and surface data indicate that Rina has become a
post-tropical cyclone. The system is embedded within low stratus
clouds, with nippy air temperatures around 45 deg F about a degree
to the northwest of the center. Interestingly, despite being over
water temperatures around 9 deg C, instability aloft is still
producing some elevated deep convection well northeast of the
center, though this is not indicative of tropical cyclone status.
The initial wind speed will stay at 40 kt, which is the maximum wind
value from a pair of recently received scatterometer passes. The
cyclone should move rather rapidly to the northeast and
east-northeast over the next day before becoming elongated and
dissipating west of Ireland. Little change in strength is
anticipated, consistent with the global models.

This is the last advisory on Rina. Additional information on this
system can be found in High Seas Forecasts issued by the National
Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01
KWBC, and available on the Web at
http://ocean.weather.gov/shtml/NFDHSFAT1.shtml

Hopefully Rina will be the finale of the extremely active 2017
Atlantic hurricane season. However that might be wishful thinking
since, of the top 10 most active hurricane seasons before this year,
seven of them still had another tropical storm after today’s date.
