There are no coastal watches or warnings in effect.

SURF: Swells generated by Paulette will continue to affect Atlantic Canada, Bermuda, the Bahamas, and portions of the east coast of the United States through tonight. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 1100 AM AST (1500 UTC), the center of PostTropical Cyclone Paulette was located near latitude 43.3 North, longitude 45.2 West. The posttropical cyclone is moving toward the eastnortheast near 35 mph (56 km/h), and this general motion is expected through Thursday. Afterward, the cyclone is forecast to slow down and turn toward the southeast and south late Thursday and Friday. Maximum sustained winds have decreased to near 85 mph (140 km/h) with higher gusts. Further weakening is forecast during the next couple of days.

Hurricaneforce winds extend outward up to 80 miles (130 km) from the center and tropicalstormforce winds extend outward up to 255 miles (405 km).

The estimated minimum central pressure is 973 mb (28.74 inches).

Conventional GOES-16 visible and enhanced BD-curve satellite imagery show that Paulette has merged with the large baroclinic zone extending over the north-central Atlantic. Deep convection just to the north of the surface center that was noted on earlier microwave images has dissipated. Therefore, the system is now classified as extratropical cyclone and this is the last NHC advisory. The initial intensity is conservatively lowered to 75 kt based on 1221 UTC scatterometer data, earlier Dvorak intensity estimates and a SATCON analysis of 64 kt.

The NHC intensity forecast is based on a blend of the global models and is just above the HCCA multi-model consensus. Although not specified in the NHC forecast, there is some chance that Paulette could reacquire tropical or subtropical characteristics later this week or over the weekend when it turns southward back over warmer oceanic temperatures. This possibility will be monitored for inclusion in future Tropical Weather Outlooks, if necessary.

The post-tropical cyclone's initial motion is east-northeastward, or 060/30 kt. The low is expected to continue quickly in this general motion through Thursday morning within the deep-layer mid-latitude flow. By mid-period, Post-Tropical Paulette is expected to slow down and turn southeastward to southward as it moves on the west side of mid- to upper-level low to the east of the cyclone. The new track forecast is based primarily on the HCCA and TVCA consensus aids.

Paulette is producing a large area of high seas. The maximum seas estimated by the Ocean Prediction Center near the core of the hurricane are up to 50 feet. Swells from Post-Tropical Cyclone Paulette have spread far away from the center and continue to affect Atlantic Canada, Bermuda, and portions of the U.S. east coast.

This is the last NHC advisory on Paulette. 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 online at ocean.weather.gov/shtml/NFDHSFAT1.php
