Forecast Summary ■ The current NHC forecast map (below left) and wind field map based on the NHC’s forecast track (below right) both show Lester moving northwest of the Hawaiian Islands at hurricane strength (74+ mph). To illustrate the uncertainty in Lester’s forecast track, forecast tracks for all current models are shown on the wind field map (below right) in pale gray. ■ Hurricane conditions are possible over Maui County and Oahu late Saturday or Saturday night, and tropical storm conditions are possible as early as Saturday afternoon. ■ Large swells generated by Lester will build across Hawaiian waters tonight and Saturday. Surf generated by these swells will peak during the weekend across the main Hawaiian Islands, becoming very large and possibly damaging along exposed shorelines. ■ Heavy rains associated with Lester may impact Maui county and Oahu Saturday and Sunday.

Tropical Storm Wind Speed Probabilities at 2 PM HST Friday September 2 for the Next 5 Days The maps below show probabilities of maximum sustained wind speeds over the next five days. The map at lower left shows the Hawaiian Islands with chances of seeing tropical storm force wind speeds (39 - 73 mph) ranging from 5% to 40%. The map at lower right shows Hawaii has less than 5% chance of seeing hurricane force wind speeds (74+ mph).

New Tropical Cyclone Potential and Average Remaining Risk NHC Estimates of New Atlantic Tropical Cyclone Formation National Hurricane Center Tropical Cyclone Formation Estimates An elongated area of low pressure continues to produce a large area of disorganized showers and thunderstorms that extend several hundred miles off the southern coast of Mexico. Upper- level winds are expected to become more conducive for development, and the disturbance should gradually consolidate during the next couple of days, with a tropical depression likely to form late this weekend or early next week while it moves west-northwestward near the coast of Mexico. Chances of formation are 70% through 2 days and 80% through five days. A weak area of low pressure located about 1000 miles southwest of the southern tip of the Baja California peninsula is producing a few showers and thunderstorms. Any development of this system should be slow to occur due to strong upper-level winds. Chances of formation are 10% through 2 days and 20% through five days.
