Oahu (Hawaii), March 22 (NationPress) Over 5,500 individuals have been forced to evacuate as the island of Oahu experiences its most severe flooding in over two decades, according to officials.
Authorities have issued warnings that heavy rainfall and thunderstorms will persist over the state of Hawaii on Saturday (local time), presenting significant hazards in Oahu and Maui County. Hawaii's Governor Josh Green stated in a video shared on X that additional rain is anticipated throughout the weekend.
"The storm is expected to bring an additional 4 to 6 inches of rain to Oahu this weekend; however, it is now moving towards Maui, where we anticipate between 4 to 8 inches, with some areas potentially receiving as much as 10 to 12 inches," Governor Green explained.
"Fortunately, there have been no reported fatalities thus far, though a few serious injuries have occurred. It is essential not to underestimate this storm," he cautioned.
The governor emphasized that conditions are perilous, as the ground is already saturated, meaning even a small amount of rain can lead to flooding, road closures, and property damage.
He informed the press on Friday that the financial impact of the storm may exceed 1 billion US dollars in estimated damages to both private and public properties, as per reports from Xinhua news agency.
While officials confirmed that over 230 individuals have been rescued during the storm, they warned of the imminent risk of a 120-year-old dam failing.
Residents were advised to evacuate the areas downstream of the Wahiawa dam, as authorities indicated it is "at risk of imminent failure."
More than 200 members of the National Guard have been mobilized during this storm to aid in rescues, implement road closures, conduct door-to-door checks, and address other public safety requirements, according to Governor Green.
Point of View
The flooding situation in Oahu is alarming, with significant evacuations highlighting the urgency for immediate response and community safety. The potential for further rainfall exacerbates the risks, necessitating robust emergency measures. The economic implications are also considerable, with estimates suggesting damages may exceed 1 billion dollars. This situation merits close monitoring.
