Tropical Storm Lala delivered drenching rain and hurricane-force gusts across Hawaii on Sunday, Aug. 16 [1].
While the storm did not make landfall, the intensity of the rainfall and wind creates a significant risk of flooding and mudslides across the islands. Residents faced hazardous conditions as the system skirted the coast.
Lala weakened to a tropical storm on Aug. 16 [1]. The eye of the system passed the southern tip of the Big Island [2], which contributed to the storm's loss of strength but failed to stop the delivery of heavy precipitation.
The weather system affected the Big Island and surrounding Hawaiian islands [3]. Though the storm remained offshore, the proximity of the eye to the southern coastline brought the most severe impacts to that region [2].
Local officials monitored the situation as the storm produced strong winds and drenching rain [4]. The system's path caused it to skirt the islands rather than move directly over them, yet the resulting gusts reached hurricane levels in several areas [1].
Emergency preparations remained in place as the storm moved through the region. The combination of high winds and saturated soil increases the likelihood of geological instability, particularly in mountainous areas of the Big Island [2].

The trajectory of Tropical Storm Lala demonstrates how a storm can cause significant disruption without making a formal landfall. By skirting the coastline, the system maintained enough energy to produce hurricane-force gusts and heavy rain, highlighting the vulnerability of Hawaii's infrastructure to near-miss tropical systems that trigger secondary disasters like mudslides.
