Tropical Storm Calvin continues to move quickly and steadily toward the Big Island.

A tropical storm warning remains in effect for Hawaii County. A tropical storm warning means means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 12 to 24 hours.

At 8 a.m., the storm was about 330 miles southeast of Hilo, packing maximum sustained winds of 45 mph with locally higher guests. Tropical-storm-force winds extend outward up to 105 miles from the center.

Winds around Calvin are expected to be generally the same through today, then are expected to gradually weaken from tonight through Thursday.

Persons in Hawaii County should complete preparations for tropical storm force wind impacts today during daylight hours prior to the onset of tropical storm conditions tonight.

From later today into Thursday, storm total rainfall amounts of 4 to 8 inches, with maximum amounts of 10 inches are possible, mainly along the windward areas of the Big Island of Hawaii.

Storm total rainfall amounts of 3 to 6 inches are expected elsewhere in the state.

This rainfall could lead to localized flash flooding and mudslides.

Surf swells generated by Calvin are expected to begin spreading across the main Hawaiian Islands later today and tonight.

This will lead to a rapid increase in surf along east facing shores, with high surf continuing into Wednesday. This elevated surf will likely cause life-threatening conditions along exposed shorelines.

Big Island residents and visitors are advised to continue monitoring official sources of information.
