Tropical Storm Surigae

Tropical Storm Surigae is packing 55-kt (65-mph) winds, moving NNW at 7 kt (8 mph). Expected to stay over open water.

TROPICAL STORM 25W (SURIGAE), LOCATED APPROXIMATELY 276 NM SOUTH OF KADENA AB, HAS TRACKED NORTH-NORTHWESTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. MINIMUM CENTRAL PRESSURE AT 251800Z IS 994 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 251800Z IS 22 FEET.— Joint Typhoon Warning Center · warning 11

This is the West Pacific · 20°N–35°N, 126°E–144°E. Surigae’s forecast track is the dotted spine — the labelled dots mark its position each day. Every cell is shaded by how many hours it spends inside Surigae’s gale-force (≥34 kt · 39 mph) wind across the whole forecast, the damaging core counted double.

Read it two ways at once. Colour is the total — the hours of gale-force wind a place piles up. A slow storm writes its danger in duration, not in any single gust, so the longer the wind sits over a place, the deeper its colour. Opacity is uniform here — this basin publishes no wind-speed-probability field, so the map claims no confidence it has not earned.

Observers following the system confirm it remains a tropical storm south-southeast of Okinawa while advancing west-northwest, aligning with the expected track and adding detail on its location far southwest of Iwo To. These updates help clarify the storm's steady movement without signs of early deviation from the official forecast.
