Typhoon Nanmadol

Typhoon Nanmadol, known in the Philippines as Typhoon Rebecca, was the 2nd strongest storm in the 2023 Pacific typhoon season. It was the costliest storm to hit Luzon since Typhoon Mangkhut (Ompong) last 5 years ago, caused Php.100bil. damages, much higher than Typhoon Haiyan in 2013. The names Nanmadol & Rebecca were ultimately retired in the spring of 2024.
