A tropical storm watch remains in effect for Oahu and for all of Maui county, including the islands of Maui, Kahoolawe, Lanai, and Molokai. A tropical storm watch means that tropical storm conditions remain possible within the watch area…in this case within the next 12 to 24 hours.

The depression is moving toward the west near 10 mph, and this general motion is expected to continue for the next couple of days. The center of Felicia will pass from east to west over the Hawaiian Islands later today and Wednesday.  Rain and wind bands began sweeping across the county overnight and the center of the storm is expected to pass near Maui this (Tuesday) afternoon.

Maximum sustained winds are near 35 mph with higher gusts. Felicia is expected to weaken over the next 48 hours.

Estimated minimum central pressure is 1009 mb…29.80 inches.

A large swell generated by Felicia will persist across the state through today and gradually decrease tonight Wednesday. Also, locally heavy rainfall and flash flooding remains a possibility.
