Both the western Pacific and the western Atlantic have seen tropical cyclones strengthening this week with Typhoon Ampil in the western tropical Pacific and Hurricane Ernesto in the western tropical Atlantic.

Ernesto is the fifth named storm to form in the tropical Atlantic in 2024 and has already caused severe disruption in Puerto Rico with almost 1 million people left without power as winds gusting more than 80mph battered the island. One weather station in Puerto Rico recorded more than 10 inches (about 250mm) of rain from Ernesto.
