Tropical Storm Calvin is expected to pass over or close to Hawaii island and south of Maui County tonight and Wednesday, according to a forecast model by the Central Pacific Hurricane Center.

Maui County will be under a flood watch and wind advisory starting today as a weakening Tropical Storm Calvin continues across the Central Pacific, bringing the potential for heavy rains and strong winds.
The storm is still projected to pass over or very close to Hawaii island and south of Maui County by Wednesday. As of 5 p.m. Monday, the storm was packing winds of 45 mph, down from 60 mph Sunday, and was moving west at 22 mph, according to the Central Pacific Hurricane Center. It was located 655 miles east-southeast of Hilo.
Hawaii island was the only one under a tropical storm warning, but weather officials warned that the rest of the state could feel impacts as well. Tropical storm-force winds can extend up to 105 miles from the center, according to the hurricane center.
With Calvin expected to produce periods of heavy rainfall for Maui and Hawaii counties, the National Weather Service issued a flood watch starting tonight through Wednesday afternoon for both counties.
Hawaii island could see rainfall of 4 to 8 inches, possibly even up to 10 inches, tonight into Thursday, mainly along the windward areas, while other islands are expected to get about 1 to 4 inches of rain, which could lead to flooding and mudslides.
Elevated runoff and overflowing streams could cause flood-prone roads and other low-lying areas to close, and urban areas may receive more significant flooding and property damage due to rapid runoff, the weather service said.
A wind advisory is also in effect today through Wednesday morning for Maui County, with northeast winds of 20 to 35 mph and gusts up to around 50 mph expected for all four islands. Winds this strong can tear off shingles, knock down tree branches, blow away tents and awnings and make it difficult to steer, especially for drivers of high-profile vehicles, the weather service said. The public is advised to watch out for falling tree branches, make sure tents and awnings are secure or taken down and be prepared for power outages.
Conditions are likely to be even more blustery at the summit of Haleakala, where east winds of 45 mph and gusts up to 55 mph are in the forecast. Winds this strong can make driving and walking difficult, and can forcefully open doors, damage hinges or slam doors shut, possibly causing injuries, the weather service said. Drivers are advised to consider postponing travel to the summit until conditions improve.
Tropical Storm Calvin is also predicted to bring in some high surf. A rapid increase in surf is expected today and Wednesday and will likely cause life-threatening surf along exposed east-facing shores, the hurricane center said.
A small craft advisory is in effect for Maui County windward and leeward waters and the Kaiwi Channel, with east winds of 20 to 30 knots and seas of 9 to 14 feet in the forecast. Inexperienced mariners, especially those in small vessels, should avoid navigating in these conditions, the weather service said.
Maalaea Bay and Pailolo Channel are also under a small craft advisory and gale watch, with northeast winds of 20 to 35 knots possible. Strong winds can cause hazardous seas, which could capsize or damage vessels and reduce visibility, the weather service said.
State and county officials have been urging residents over the past few days to be prepared and to have an emergency supply kit to last two weeks and an emergency plan just in case family members are separated.
