CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for...
- Bermuda A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 24 hours. For storm information specific to your area, please monitor products issued by your national meteorological service.

WIND: Tropical storm conditions are possible today across Bermuda and the nearby waters, particularly to the south of the island.

SURF: Swells generated by Henri are expected to affect Bermuda during the next day or so. Please consult products from the Bermuda Weather Service for more details.

At 1100 AM AST (1500 UTC), the center of Tropical Storm Henri was located near latitude 30.4 North, longitude 64.3 West. Henri is moving toward the west southwest near 6 mph (9 km/h). A faster motion toward the west is forecast by tonight, followed by a motion to the west northwest or northwest by late Thursday. On the forecast track, the center of Henri should pass well to the south of Bermuda through tonight. Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Some strengthening is possible during the next day or so. Tropical storm force winds extend outward up to 35 miles (55 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches).

Henri remains a sheared tropical storm. Geostationary satellite images and microwave data show a relatively large area of deep convection (~200 miles across), but the center of the storm is located near the western edge of the thunderstorms due to ongoing northwesterly vertical wind shear. The latest Dvorak estimates have been steady at 3.0/45 kt from TAFB and SAB, and based on that data, the initial intensity is held at 45 kt. The center of Henri is located roughly 130 miles south-southeast of Bermuda currently, and this will likely be as close as the storm gets to the island.

The tropical storm is gradually turning to the west, as expected, and the initial motion is estimated to be 255/5 kt. A subtropical ridge over the western Atlantic is building eastward to the north of Henri, and this feature should steer the storm westward at a slightly faster pace during the next two or three days. After that time, the ridge is expected to weaken and shift farther east as a cut off low or negatively-tilted trough develops over the northeast U.S. This change in the steering pattern should cause Henri to turn northeastward between Bermuda and the east coast of the U.S in the 72-120 h period. The NHC track forecast is a little faster than the previous one in the short term and farther west than the previous one from days 3-5, trending toward the latest consensus models.

The northwesterly shear currently affecting Henri is expected to subside later today, and that should allow the storm to gain strength during the next 12-24 hours. However, a round of moderate northerly shear is expected to setup over Henri during the 24-96 hour period. Although this shear would typically cause some weakening, the combination of warm SSTs and increasing mid-level moisture could offset the negative influences of the shear. Therefore, no change in strength is predicted beyond the 24 h period. Some of the models suggest that the shear could lessen again this weekend, so although not explicitly forecast, some strengthening is possible then.
