Over the last 24 hours, Tropical Cyclone Amos has undergone a period of rapid intensification. The storm has increased by about 30 knots, from yesterday’s 45 knots to the current max sustained winds of 75 knots. Conditions seem to support continued intensification over the next 48 hours.
The tropical cyclone is currently located approximately 441 miles west-northwest of Pago Pago, the capital of American Samoa. The current forecast track shows the system passing about 90 to 100 miles south of Pago Pago with gale-force winds just skirting American Samoa.

This color enhanced infrared image, provided by the Himawari-8 satellite, shows Amos spinning in the South Pacific Ocean. The first unit of JMA’s third generation of geostationary satellites, Himawari-8, became operational on July 7, 2015. Providing visible light and infrared images of the Asia-Pacific region, data provided by the satellite are vital for complete global geostationary coverage.
NOAA and JMA have mutual back-up arrangements for geostationary systems, with the GOES-R and Himawari satellite series carrying similar advanced imagers. The satellite gives us a preview of what we can expect from NOAA’s GOES-R satellite after it launches in October 2016!
