1. Large swells generated by Larry will continue to affect the Lesser Antilles, portions of the Greater Antilles, and the Bahamas through midweek. Significant swells should reach the east coast of the United States and Atlantic Canada by midweek and continue affecting these shores through the end of the week. These swells will likely cause life-threatening surf and rip current conditions, and beachgoers and other interests along these coasts are urged to follow the guidance of lifeguards and local officials this week.

2. The center of Larry is forecast to pass east of Bermuda on Thursday, but given Larry's large size, tropical storm conditions are possible there Thursday, along with a risk of heavy rainfall and coastal flooding. A Tropical Storm Watch is in effect for Bermuda and interests there should closely monitor the latest forecast updates.

3. Larry is forecast to move near or over portions of southeastern Newfoundland late Friday and Friday night as it transitions to a hurricane-force post-tropical cyclone. There is a risk of impacts from high winds, rainfall, and storm surge in portions of Newfoundland, and interests there should monitor the progress of Larry and updates to the forecast.

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, generally within 48 hours. For storm information specific to your area, please monitor products issued by your national meteorological service.

Key messages for Larry can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

WIND: Tropical storm conditions are possible on Bermuda beginning late Wednesday or early Thursday.

SURF: Swells generated by Larry will continue to affect the Lesser Antilles, portions of the Greater Antilles, and the Bahamas through midweek, and impact Bermuda through the end of the week. Significant swells should reach the east coast of the United States and Atlantic Canada by midweek and continue affecting these shores through the end of the week. These swells are likely to cause life threatening surf and rip current conditions. Please consult products from your local weather office.

At 500 PM AST (2100 UTC), the center of Hurricane Larry was located near latitude 25.1 North, longitude 56.3 West. Larry is moving toward the northwest near 9 mph (15 km/h), and this general motion is expected to continue through Wednesday. A turn toward the north northwest and north with an increase in forward speed is forecast on Thursday. On the forecast track, the center of Larry should pass east of Bermuda on Thursday. Maximum sustained winds remain near 115 mph (185 km/h) with higher gusts. Larry is a category 3 hurricane on the Saffir Simpson Hurricane Wind Scale. Slow weakening is forecast during the next several days. Larry is a large hurricane. Hurricane force winds extend outward up to 70 miles (110 km) from the center and tropical storm force winds extend outward up to 185 miles (295 km). The minimum central pressure reported by a NOAA Hurricane Hunter aircraft is 965 mb (28.50 inches).

After becoming rather ragged-looking in earlier satellite images, Larry's eye has become a little better defined recently, and the surrounding deep convection is more or less maintaining its strength. Observations from a NOAA Hurricane Hunter aircraft show that the central pressure has fallen slightly, to 965 mb. Peak flight-level winds from the aircraft were 110 kt so the advisory intensity is kept at 100 kt. This is also consistent with a Dvorak Current Intensity number from TAFB.

Larry continues its northwestward motion at about 320/8 kt. The hurricane should move around the western side of a deep-layer subtropical anticyclone during the next 48-60 hours. After passing Bermuda, the system is likely to accelerate northeastward while moving into the mid-latitude westerlies ahead of a trough moving from the northeastern United States to Atlantic Canada, and move into the far north Atlantic by day 5. The official track forecast stays close to the previous NHC prediction, and remains in good agreement the various model consensus solutions.

The hurricane continues to exhibit well-defined upper-level outflow, indicative of weak vertical shear. Over the next couple of days, Larry will be traversing waters of gradually decreasing oceanic heat content. This, combined with some dry mid-level air in the environment, should lead to a gradual decrease in intensity through 48-60 hours. Later in the forecast period, colder waters and strong shear should cause more rapid weakening. By day 4, the global models show Larry merging with a frontal zone. Therefore, the NHC forecast calls for extratropical transition by that time. The official intensity forecast is generally below the statistical-dynamical guidance and above the coupled dynamical hurricane models through 72 hours, but in good agreement with the model consensus aids.
