DISCUSSION AND OUTLOOK
At 1100 AM AST (1500 UTC), the center of Hurricane Larry was located
near latitude 32.0 North, longitude 61.6 West. Larry is moving
toward the north-northwest near 16 mph (26 km/h), and a turn toward
the north with an increase in forward speed is forecast today, with
a faster northeastward motion expected by Friday. On the forecast
track, the center of Larry will pass east of Bermuda today, and
move near or over southeastern Newfoundland Friday night or early
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Gradual weakening is forecast during the next couple of
days, but Larry is expected to remain a hurricane during that time.
Larry should become an extratropical cyclone early Saturday, after
passing by Newfoundland, then weaken further while it passes
southeast of Greenland Sunday night. Larry is expected to be
absorbed by a larger extratropical low east of Greenland by Monday.

up to 90 miles (150 km) from the center and tropical-storm-force
