Weather tracker: Japanese islands brace for Dujuan to become a typhoon again

Storm system expected to hit Izu Islands as it strengthens. Meanwhile, Atlantic hurricane season is unusually quiet

Tropical Storm Dujuan is skirting the coast of Japan and despite avoiding a direct landfall, is still expected to leave its mark. Dujuan briefly reached typhoon status on Friday before weakening to a tropical storm again on Sunday morning. But it is expected to restrengthen back to a typhoon by Tuesday morning. Sustained winds could reach 80mph (129km/h), with gusts approaching 100mph.

Although mainland Japan has avoided a direct hit, Dujuan’s track takes it across the Izu Islands, where evacuation warnings are in place. Heavy rain, flooding and landslide alerts are widespread, with high waves adding another threat to exposed coastal areas and islands.
