Hawaii Extended Forecast Discussion
NWS Weather Prediction Center College Park MD
336 AM EDT Fri Aug 14 2026

Valid 00Z Sat 15 Aug 2026 - 00Z Sat 22 Aug 2026

Primary focus through the weekend will be on the advancement of
now Tropical Storm Lala as the cyclone heads on a west-northwest
heading towards the Big Island of Hawaii. For more information on
TS Lala and expected impacts from the tropical cyclone, please
visit the National Hurricane Center for the latest on the storm as
it makes headway towards the island chain. 

Timing of the most impactful period from Lala will occur on 
Friday through Saturday with the backside of the storm still 
likely to maintain trailing bands in its wake before finally 
ceasing as we step into Monday. Beyond the weekend, expecting a 
return to a predominant northeast trade wind setup with passing
showers on the windward side of the islands leading to additional
rainfall over top what will be very saturated grounds in wake of
Lala. The next several days will provide heightened threats of
flash flooding compared to normal, so please be sure to monitor
the local forecast from the Honolulu WFO for the latest.
