Tropical Storm Lala brought torrential rain and hurricane-force gusts to the Hawaiian Islands on Sunday, Aug. 16 [4].
The storm caused significant infrastructure damage and utility failures across the archipelago. While the system did not make direct landfall, the intensity of the rainfall and wind created hazardous conditions for residents and emergency responders.
Lala was downgraded from a hurricane to a tropical storm as it moved through the region [1]. The storm's eyewall skirted the islands, which allowed the system to deliver intense weather without a direct hit [1]. The Big Island experienced particularly severe impacts from the system [1].
Rainfall totals were extreme in several locations. Some areas recorded rain accumulation of nearly three feet [1]. This deluge led to flooding and contributed to the widespread damage reported across the islands.
Utility companies said that thousands of residents were without power [2]. The combination of heavy rain and strong gusts downed power lines and trees, complicating recovery efforts on Sunday [2].
Property damage was also extensive. At least 100 homes were damaged by the storm's effects [2]. Local officials worked to assess the full scale of the destruction as the weather system began to move away from the islands.
The storm's path highlighted the vulnerability of the islands to systems that do not necessarily make landfall. Even without a direct center-hit, the outer bands of Tropical Storm Lala proved capable of causing significant disruption to the power grid, and residential housing [1], [2].
“Rain accumulation reached nearly three feet in some locations”
The impact of Tropical Storm Lala demonstrates that a storm's category or landfall status does not always correlate with the level of destruction. By skirting the islands rather than making a direct hit, the storm still managed to deliver catastrophic rainfall and wind, underscoring the persistent risk that tropical systems pose to Hawaii's infrastructure regardless of their exact trajectory.
