While the hurricanes are not expected at this point to affect the mainland, NWS has warned that Hawaiian offshore waters beyond 40 nautical miles out to 240 nautical miles, including the portion of the Papahanaumokuakea Marine National Monument east of French Frigate Shoals, will be affected. The Weather Channel reports that it could pass near Hawaii as well but it is too early to tell.
While Hurricane Erick is forecast to pass south of the Hawaiian Islands and Tropical Storm Flossie approaches from the Eastern North Pacific, Mayor Michael Victorino is urging residents to be vigilant, stay informed and prepare.
"For now, we are forecasting an increase to moisture levels, clouds and showers; starting over the Big Island by late Thursday and spreading westward to the smaller islands into the weekend", the weather service said. Erick is a Category 4 and Flossie is a 1. Current tracking has the heart of the storm passing along the south side of the island chain, possible sparing Hawaii from the heaviest wind and rainfall.
However, like Hurricane Erick, Flossie is not expected to hit land in Hawaii - although it's likely to deliver even more rain and rough seas.
As it stands, Hurricane Erick is moving toward the west at near 12 miles per hour (19 kilometers per hour), with maximum sustained winds near 125mph (205kph). According to the Sun-Sentinel, the storms only have a 10 percent chance of developing into tropical cyclones. "These additional local island-by-island impacts are highly dependent upon the size, intensity, and track of Erick as it moves through the Hawaii region". But, they are expected to cross directly over Puerto Rico, the Virgin Islands, Hispaniola, and parts of the southeastern Bahamas.
