At 1100 PM AST (0300 UTC), the center of Tropical Storm Paulette was located near latitude 17.8 North, longitude 42.5 West. Paulette is moving toward the northnorthwest near 5 mph (7 km/h). The storm is forecast to turn toward the northwest and move faster on Tuesday, and move westnorthwestward or westward on Wednesday and Thursday.

Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Some strengthening is forecast during the day or two, with little change in strength expected afterward through Thursday.

Tropicalstormforce winds extend outward up to 80 miles (130 km) from the center.

The estimated minimum central pressure is 1004 mb (29.65 inches).

lite images show that Paulette continues to become better organized, with a more symmetric presentation and very deep convection near or just north of the center. The initial wind speed is increased to 40 kt, a little higher than recent subjective Dvorak estimates, but close to the objective estimates and the UW-CIMSS satellite consensus. Further strengthening is expected during the next day or so while the storm remains in a warm SST and low-to-moderate shear environment. By midweek, some weakening is forecast due to an increase in shear from an enhanced mid-oceanic upper-level trough. There's a fair amount of uncertainty on how quickly the tropical cyclone moves across the trough axis, which would then allow Paulette to find an area of lighter shear, plus very warm water, by the end of the forecast period. The intensity forecast is slightly higher in the short-term, and lower in the day-4 period just before the environment is forecast to improve.

Paulette appears to be moving slowly north-northwestward this evening. A mid-level ridge is likely to build over the western and central North Atlantic in a day or two, and this pattern should cause Paulette to move faster toward the northwest tomorrow, and west-northwestward or westward through late week. A turn back toward the west-northwest or northwest is possible over the weekend as the cyclone reaches the western periphery of the ridge. This is not a particularly certain forecast because the track models aren't in good agreement, perhaps linked to the strength of Paulette, and there is significant spread in the various ensemble guidance. With no clear trends to rely on, and since the new model consensus came in very close to the previous NHC forecast, the new NHC track prediction is basically unchanged from the previous one.
