EFFECTS & HAZARDS
KOMPASU's strong circulation remains well-organized w/ an established cloud-filled, ragged eye. In just a few hours, the Northwestern Eyewall is expected to reach Okinawa and nearby islands of Ryukyu. Tropical Storm Conditions are now occurring over Okinawa and Ryukyu Islands...increasing to Typhoon Conditions in the next few hours...stronger winds with higher gusts are likely over elevated terrains of Okinawa & Ryukyu Islands Click here to view the latest NOAA-CIRA's Wind Analysis. 6-hr total rainfall amounts of 5 up to 100 mm (light to moderate rain) can be expected along its rainbands...with isolated amounts of up to 120 mm (Moderate) near the center of Kompasu or along the southern eyewall. Click here to view the latest NOAA's eTRaP graphic on the storm's rainfall amount. Under Tropical Storm Conditions, storm surge heights may reach 1 to 3 feet (0.3 to 0.9 meters) above ground level w/ large and dangerous battering waves...increasing to 6 or 8 feet (1.8-2.6 meters) during Typhoon Conditions...especially along the beaches of Okinawa and Ryukyu Islands today.
