Aloha UH Hilo Faculty, Staff, and Students:

Please be advised that as of 11 am today, Sunday July 26, Hurricane Douglas is approximately 55 miles east-northeast of Kahului, Maui, tracking west-northwest at 16 mph as a Category 1 hurricane, with maximum sustained winds of 85 mph. This motion is expected to continue for the next couple days. On the forecast track, Hurricane Douglas will pass near, or over, the islands from Maui to Kauai today and tonight.

A Tropical Storm Warning is in effect for Hawaii island. A Hurricane Warning is in effect for the rest of the state. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case imminently on Hawaii island.

While the most dangerous impacts of the storm seem to have passed Hawaii island, please stay vigilant and safe. Possible impacts for Hawaii Island include:

WIND: Tropical Storm conditions are imminent across portions of Hawaii island. Due to the steep terrain of the islands, hurricane-force wind gusts are possible even within the tropical storm warning area. Hurricane conditions are expected in portions of Maui County today, on Oahu by this afternoon, and on Kauai and Niihau tonight.

SURF: Large swells generated by Hurricane Douglas will affect the Hawaiian Islands into Monday, producing life-threatening and potentially destructive surf along exposed shores.

STORM SURGE: The combination of higher than predicted water levels, dangerous storm surge, and large breaking waves will raise water levels by as much as 3 feet above normal tides near the center of Hurricane Douglas.

RAINFALL: Heavy rainfall associated with Hurricane Douglas is expected to affect portions of the main Hawaiian Islands today into Monday. Total rain accumulations of 5 to 10 inches are possible from Maui County westward to Kauai County, with the greatest amounts up to 15 inches in elevated terrain. This rain may result in life-threatening flash flooding and land slides, as well as rapid water level rises on small streams. Hurricane Douglas could produce an additional 2 to 4 inches of rainfall over the northern half of Hawaii island.

As conditions warrant, we will send out announcements or alerts via email, and notifications will be posted on the UH Hilo website and social media.  All members of the UH community are encouraged to sign up for UH Alert to receive emergency text alerts. If you have already signed up, log in to ensure that your contact information is up to date.

Additional information can be found at the National Hurricane Center.

Additionally, information on hurricane preparedness can be found at the Federal Emergency Management Agency (FEMA) website Ready.

The UH Hilo Emergency Guidebook App is also now available and may be downloaded.

We continue to monitor Hurricane Douglas and are working closely with Hawai‘i County Civil Defense as well as other county and state agencies to remain prepared and informed.

Mahalo, and stay safe.
