Dangerous Cyclone Ilsa to make landfall this evening – Tropical Weather Bulletin – April 13, 2023


Cyclone Ilsa has intensified markedly since yesterday, and is now a strong Category 3 storm on the Saffir-Simpson Scale, making it a borderline Category 5 cyclone on the Australian scale. Further intensification is likely up to shortly before landfall, expected in the early evening today. Ilsa ravaged the Rowley Shoals in the last couple of hours with a pressure recording in the lower 940s, and winds of at least 100 miles per hour (160kph). The storm’s winds will increase to over 200kph by landfall, with a powerful storm surge and up to 250mm of rainfall expected in the area along Eighty Mile Beach and possibly closer to Port Hedland.

Elsewhere, Tropical Storm Amang has dissipated over the Philippines, with only modest amounts of residual rainfall expected over central and northern Luzon. Further out to sea, an area of interest could develop next week near Chuuk and Pohnpei, in Micronesia.
