Hurricane Watch Threatens Big Island Saturday Flights

HILO, Hawaii - Hawaii County was placed under a Hurricane Watch early Thursday as Tropical Storm Lala moved toward the Big Island, bringing the possibility of hurricane conditions, dangerous flooding and delays to Saturday flights.

The watch was issued at 5:00 a.m. HST on Thursday, Aug. 13, 2026, according to The Associated Press. At that time, Lala's center was about 705 miles east-southeast of Hilo, with maximum sustained winds of 40 mph.

The storm was moving west at 10 mph. Tropical-storm-force winds extended up to 140 miles from its center, the AP reported.

A hurricane watch does not mean hurricane conditions are certain. It means they are possible within the designated watch area. The alert is generally issued about 48 hours before anticipated tropical-storm-force winds could make outdoor preparations difficult or dangerous.

Tropical Storm Lala Could Strengthen Before Saturday

Forecasters said Lala could be near hurricane strength as it approaches the Big Island. Hurricane conditions were possible by early Saturday, according to a National Hurricane Center advisory cited by Bloomberg.

The storm was located near 15.2 degrees north latitude and 145.5 degrees west longitude when the watch was issued, according to the AP. Its location, westward movement and potential strengthening place the Big Island at the front of the expected weather impacts.

Forecast uncertainty remains important. A hurricane watch is a preparation signal, not a declaration that every part of the island will experience the same conditions. Travelers should nevertheless treat Saturday plans as vulnerable, particularly when those plans depend on tightly timed flight connections or ground transportation.

Saturday Flights Face Growing Disruption Risk

Travel-focused concern centers on Friday and Saturday flights serving the Big Island. No blanket cancellation order is implied by the hurricane watch, but the combination of strengthening winds, heavy rainfall and dangerous coastal conditions creates a credible risk of delays or broader transportation disruption.

Reuters reported that the first significant rainfall could reach the Big Island on Friday before spreading to Maui on Saturday and the rest of the islands later in the weekend. That timing places Saturday departures and arrivals directly inside the period when conditions may be deteriorating.

Passengers booked to fly Friday or Saturday should monitor airline notifications, flight status pages and official weather advisories rather than relying on the original schedule. Before paying a change fee, travelers should also ask their airline whether a weather waiver applies to the booking. Previous waivers associated with July's Hurricane Fausto may not apply because Lala is a separate storm system.

Travelers connecting between islands need to watch conditions beyond the Big Island. The current watch is focused on Hawaii County, but the rainfall forecast extends across much of the island chain, and Reuters reported that impacts could move west during the weekend.

Flooding, Mudslides and Dangerous Surf

Wind is only one part of the risk. Forecasters expected rainfall totals of 5 to 10 inches across much of Hawaii, with localized amounts up to 20 inches, according to the AP. Reports warned that the rainfall could produce life-threatening flooding and mudslides.

Storm-generated swells were expected to reach east-facing shores Friday and build through the weekend. Those swells could create life-threatening surf and rip currents, adding another concern for visitors with coastal activities or shoreline travel planned.

A storm surge of 1 to 3 feet was possible if the peak surge coincided with high tide, the AP reported. Travelers should not interpret a relatively modest wind reading at a hotel or airport as proof that nearby roads, beaches or low-lying areas are safe. Rainfall and coastal hazards can vary sharply across an island with complex terrain.

Saturday Is Now the Decision Point

In my assessment, the hurricane watch is enough to change how travelers should manage a Big Island trip, even before an airline posts a cancellation. The wrong move is to assume that a ticketed flight will operate normally until told otherwise. The better approach is to preserve flexibility, avoid unnecessary prepaid changes and keep checking the carrier's waiver rules.

The forecast rainfall deserves at least as much attention as Lala's wind category. Totals of 5 to 10 inches, with up to 20 inches possible in some areas, can turn a straightforward airport transfer into a far less predictable trip. Travelers staying away from the airport should allow for the possibility that local road conditions, not the flight itself, become the immediate obstacle.

I would also avoid building a Saturday itinerary around a same-day connection that cannot absorb a delay. That is not a prediction that flights will be canceled. It is a recognition that the Big Island may be dealing with worsening weather while Maui and other islands begin seeing impacts of their own.

The situation remains fluid, and the watch is precautionary. Still, this is not the weekend to ignore airline messages, head toward dangerous surf for photographs or wait until conditions deteriorate before adjusting plans. Monitor official advisories, confirm flight status directly with the carrier and make any necessary preparations while travel and outdoor movement remain manageable.
