What happened

On August 13, 2026, Tropical Storm Lala was named as it moved across the central Pacific, prompting a hurricane watch for parts of Hawaii's Big Island. The National Weather Service (NWS) in Honolulu issued warnings about the potential for life-threatening flooding and damaging winds, with maximum sustained wind speeds recorded at 40 miles per hour. Forecasters predict that Lala could strengthen to near-hurricane status by early Saturday, with sustained winds expected to reach between 45 to 60 mph and gusts up to 75 mph. The storm is anticipated to bring heavy rainfall, with forecasts estimating an additional 5 to 10 inches, which could lead to extreme flooding, mudslides, and rockslides in mountainous areas. Residents in affected regions are urged to prepare for possible evacuations and to monitor updates closely as the storm approaches. The NWS has highlighted that the greatest threat from Lala is heavy rainfall, which could overwhelm rivers and streams, inundate homes and businesses, and make travel dangerous or impossible. As the storm nears, conditions may also become favorable for isolated tornadoes, adding to the potential hazards. The situation remains dynamic, and officials are closely monitoring the storm's path and impacts.
