DISCUSSION

1. Paulette is expected to approach Bermuda as a hurricane this weekend and make its closest approach to the island on Monday and Tuesday. While the exact details of Paulette's track and intensity near the island are not yet known, the risk of strong winds, storm surge, and heavy rainfall on Bermuda continues to increase.

2. Swells produced by Paulette are expected to affect portions of the Leeward Islands, the Greater Antilles, the Bahamas, Bermuda, and the southeastern United States into the weekend. These swells could cause life-threatening surf and rip current conditions.

There are no coastal watches or warnings in effect.

Interests in Bermuda should monitor the progress of Paulette. Please consult products from your local weather office.

Key messages for Paulette can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT2 KNHC. SURF: Swells generated by Paulette are expected to reach portions of the Leeward Islands tonight and Friday and will continue to spread westward to portions of the Greater Antilles, Bahamas, Bermuda, and the southeastern United States into the weekend. These swells are likely to cause lifethreatening surf and rip current conditions. Please consult products from your local weather office.

At 500 PM AST (2100 UTC), the center of Tropical Storm Paulette was located near latitude 22.1 North, longitude 50.1 West. Paulette is moving toward the westnorthwest near 9 mph (15 km/h). A westnorthwestward or northwestward motion with some increase in forward speed is expected through the weekend.

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some slight weakening is expected during the next day or so, but Paulette is then forecast to restrengthen by Saturday. Paulette is expected to become a hurricane by Sunday.

Tropicalstormforce winds extend outward up to 205 miles (335 km) from the center.

The estimated minimum central pressure is 997 mb (29.44 inches).

Continuous bursts of deep convection have been ongoing to the north and northeast of Paulette's center of circulation, with the cyclone being affected by nearly 40 kt of deep-layer southwesterly shear. The highest intensity estimates are Dvorak classifications of T3.0/45 kt from TAFB and SAB, and that value remains the initial intensity. The shear should reach its peak magnitude this evening, which is likely to cause Paulette to weaken slightly during the next 24 hours. However, gradual re-strengthening is forecast to begin in about 36 hours, and the rate of intensification is expected to increase in 2 to 3 days when the shear could fall to 10 kt or less, along with a more unstable atmosphere and warmer sea surface temperatures. Paulette is now forecast to become a hurricane by day 3 and continue to intensify through the end of the forecast period. As was advertised in the previous forecast package, the new NHC forecast intensities have been bumped up on days 3 through 5 and now lie near or just below the IVCN intensity consensus and the HCCA corrected consensus aid.Paulette's heading over the past 6-12 hours has been toward the west-northwest, or 300/8 kt. The cyclone's trajectory is expected to oscillate between northwest and west-northwest for the next 4 days, being dictated by the strength of the subtropical ridge to the north and the depth of the steering flow depending on Paulette's intensity. The updated NHC track forecast during this period has been nudged a bit to the north, mostly to account for an adjustment of the initial position. The model guidance all agree that Paulette should turn northward around the western side of a central Atlantic high pressure area by day 5, with the expected hurricane likely to make a tight recurvature near Bermuda. There remains some uncertainty on exactly where that turn will occur, but for now the NHC forecast lies between the tighter-turning ECMWF and HCCA models and the more gradually-turning GFS and HWRF models.
