DISCUSSION

1. Large swells generated by Larry are expected to reach the Lesser Antilles today and will spread to portions of the Greater Antilles, the Bahamas, and Bermuda on Monday and Tuesday. Significant swells will likely reach the east coast of the United States and Atlantic Canada by midweek. 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 advice of lifeguards and local officials this week.

2. Larry is forecast to approach Bermuda during the next several days, likely as a major hurricane, bringing a risk of strong winds, heavy rainfall, and coastal flooding to the island by the middle of this week. While it is too soon to determine the magnitude of these hazards and potential impacts on Bermuda, interests there should closely monitor the latest forecast updates during the next several days.

SURF: Swells generated by Larry are expected to reach the Lesser Antilles today, and will spread westward to portions of the Greater Antilles, the Bahamas, and Bermuda on Monday and Tuesday. Significant swells will likely reach the east coast of the United States and Atlantic Canada by midweek. These swells are likely to cause life threatening surf and rip current conditions.

At 1100 AM AST (1500 UTC), the eye of Hurricane Larry was located near latitude 19.5 North, longitude 49.7 West. Larry is moving toward the northwest near 13 mph (20 km/h). A northwestward motion with a slight decrease in forward speed is expected during the next few days. Maximum sustained winds are near 125 mph (205 km/h) with higher gusts. Larry is a category 3 hurricane on the Saffir Simpson Hurricane Wind Scale. Little change in strength is forecast during the next few days, although fluctuations in intensity will be possible. Larry is expected to remain a major hurricane through the middle of this week. Larry is a large hurricane. Hurricane force winds extend outward up to 45 miles (75 km) from the center and tropical storm force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 955 mb (28.20 inches).

Larry continues as a large and intense hurricane this morning, with a 40 n mi diameter eye surround by cloud tops to near -80 deg C. There are, however, some breaks in the cold tops over the northern portion of the circulation. The current intensity is adjusted slightly to 110 kt, based on a blend of subjective Dvorak estimates from TAFB and SAB along with objective ADT estimates from UW-CIMSS. Upper-level outflow remains somewhat restricted over the southwestern quadrant of the system, indicative of at least slight vertical shear. This shear is probably being caused by the flow to the east of an upper-level low to the north of Puerto Rico. The low is forecast to move northwestward over the next few days, possibly lessening the shear over Larry.

The hurricane is moving northwestward at a slightly slower speed, or 310/11 kt. Larry is likely to continue its northwestward trek along the southwestern periphery of a mid-tropospheric anticyclone during the next 2-3 days, with only a slight reduction in forward speed. Around 96 hours, the hurricane is forecast to turn toward the north-northwest and north while rounding the western side of the ridge. By the end of the forecast period, Larry is expected to begin its recurvature into the mid-latitude westerlies. The new official forecast track essentially follows the previous one, and is also very close to the latest NOAA corrected consensus and Florida State University Superensemble guidance.

Larry's large eye suggests that no rapid changes in strength are likely during the short term. Since vertical shear is not expected to increase and the system will be traversing warm waters, the hurricane should be able to more or less maintain its intensity during the next few days. One inhibiting factor is the presence of relatively dry mid-level air in the environment. The official intensity forecast is on the high side of the model guidance and keeps Larry as a major hurricane through 72 hours.
