The Central Pacific Hurricane Center in Honolulu has continued the TROPICAL STORM WATCH for MAUI COUNTY.
A Tropical Storm Watch means that tropical storm conditions are possible within the watch area within 48 hours.
EFFECTS: At 5:00 a.m. the center of Hurricane Iselle was located near latitude 17.0 north, longitude 144.5 west, or about 720 miles east-southeast of Hilo, Hawaii. Hurricane Iselle is moving west-northwest at 15 mph with maximum sustained winds near 85 mph. View the latest animated satellite loop of Iselle here.
Iselle is expected to bring heavy rains, high surf and strong winds. Tropical storm conditions could reach Maui County late on Thursday. High surf is expected to reach the island ahead of the heavy rains and strong winds.
Swells generated by Iselle are expected to reach the main Hawaiian islands today, possibly damaging along some coastlines starting late tonight or Thursday. Surf will steadily increase along the Maui windward coast today, and reach hazardous levels as the storm approaches. Surf heights of 10 to 20 feet are expected Thursday ahead of Iselle with larger surf Thursday night and Friday. Astronomical high tide is also expected. High tide Thursday for Hana is 2.7 feet at 1:42 p.m. and 2.9 feet at 2:18 p.m. on Friday. The high surf and high tide combination will bring the potential for coastal flooding along low lying areas.
The latest forecast is for sustained winds of 40 mph or higher for portions of Maui County from Thursday night to late Friday morning. Depending on the exact tract of Iselle, there is the possibility of moderate wind damage.
With some uncertainty in the exact track and strength of Iselle, it is still too early to determine which islands is at most risk from Iselle. However, the Big Island and Maui County will be the first areas to experience the impacts of Iselle.
A FLASH FLOOD WATCH IS ALSO IN EFFECT FOR THE STATE OF HAWAII FROM THURSDAY, 4:00 AM TO SATURDAY, 6:00 AM.
