Hurricane Barbara is centered as of 8 a.m. PDT about 1080 miles (1740 km) southwest of the southern tip of Baja California. It’s moving toward the west-northwest near 14 mph (22 km/h).
Satellite data indicate that the maximum sustained winds have increased to near 130 mph (215 km/h) with higher gusts – a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km). Some additional strengthening is possible today, but weakening is likely to begin on Wednesday and continue into Thursday.
Trade winds continue Tuesday, with lighter winds for Wednesday and the Fourth of July. A few trade wind showers in the morning today mainly for windward spots. Mostly Sunny afternoon. Highs in the upper 80s to lower 90s for Central and West Maui. Middle 80s windward. Winds will be east at 10-15 mph. Hurricane Barbara is gaining strength in the Eastern Pacific and will be monitored as it eventually tracks toward the Central Pacific. Strengthening is expected in the short term, with long term weakening anticipated as it eventually hits cooler waters, drier air and some possible wind shear. It’s too early to say whether what’s left of the system will bring any impacts to Maui outside of increased surf for Eastern Shores.
