At 1100 PM AST (0300 UTC), the center of Tropical Storm Bill was located near latitude 36.7 North, longitude 69.8 West. Bill is moving toward the northeast near 23 mph (37 km/h), and this general motion is expected through Wednesday with increasing forward speed. Satellitederived wind data indicate that the maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Some additional strengthening is possible on Tuesday, however the system is expected to become a posttropical low and dissipate on Wednesday.

Tropicalstormforce winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1003 mb (29.62 inches).

Deep convection has increased in a cluster to the northeast of the estimated center. Scatterometer measurements showed a couple of 40-41 kt vectors over the southeastern quadrant of the cyclone. On this basis, the estimated intensity is increased to 40 kt, which makes this the second tropical storm of the season, albeit a rather high-latitude one. The system is in an environment of fairly strong southwesterly shear, but the diffluent upper-level flow has apparently contributed to some strengthening in a seemingly hostile environment. Some additional short-term strengthening could occur but by 36 hours, the cyclone should merge with a baroclinic zone while approaching Newfoundland and become extratropical. This transition is also shown by the FSU cyclone phase analyses of the GFS model fields.

Bill is moving fairly swiftly northeastward, or 055/20 kt. The track forecast appears to be straightforward. The flow ahead of a large mid-tropospheric trough near the United States east coast should accelerate the system northeastward for the next day or two, and until the system dissipates. The NHC track forecast is similar to the previous one and not far from the model consensus.
