A tropical storm warning has been issued for Maui County. The upgrade from “watch” to “warning” means that tropical storm conditions are expected in the warning area within 36 hours. A Tropical Storm Warning was issued for the Big Island earlier today. The entire state remains under a Tropical Storm Watch until Saturday. That, too, may be extended if Hurricane Julio remains on its current path.
EFFECTS: Tropical storm conditions are expected for Maui County Thursday night.
Swells generated by Iselle will reach the main Hawaiian Islands today, with large damaging surf expected along mainly east and south shores starting late tonight or Thursday.
Iselle is expected to produce rainfall amounts of 5 to 8 inches, with isolated maximum amounts to 12 inches. These rains could cause life-threatening flash floods and rock and mud slides.
The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters. The surge will be accompanied by large and damaging waves. Surge related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.
A FLASH FLOOD WATCH IS ALSO IN EFFECT FOR THE STATE OF HAWAII FROM THURSDAY, 4:00 AM TO SATURDAY, 6:00 AM.
