Tropical Storm Iselle Floods Hawaii
Downgraded from a hurricane, Tropical Storm Iselle will bring heavy rain and damaging winds to Hawaii today.
The Big Island was put under a hurricane warning, the first since 1993.
Iselle will continue moving west, dropping large amounts of rain on Maui and The Big Island, as well as rain for the rest of the state.
The tropical storm will make its exit later today, but another hurricane could threaten the state.
Hurricane Julio strengthened to a major hurricane with winds at 120 mph sustained.
The track of Julio takes the hurricane north of Hawaii on Sunday, but the forecast path should be monitored.
