Get typhoon updates today on a live radar map of every storm from the Philippines to Japan.
RainViewer shows every active typhoon in the western Pacific on a live radar map, from the Philippines to Taiwan, China, and Japan. New scans from 1000+ radar stations worldwide reach the map as they arrive. Follow typhoon rain bands as they approach land, and open any storm below for its wind speed and path.

Typhoons reach land across some of the densest radar networks in the world, from the Philippines to Japan. RainViewer combines those stations into one live map. The outer rain bands show up on RainViewer hours before the typhoon's center makes landfall.
Replay the last 48 hours of radar to see how a typhoon's rain bands shifted. Then check the 2-hour radar forecast for your own street.
Much of a typhoon's damage comes from rain, through flooding and landslides. RainViewer Rainfall Totals shows how much rain has fallen over any window, up to 48 hours back.

The Japan Meteorological Agency ranks western Pacific storms by 10-minute sustained wind speed.
Tropical Depression (under 63 km/h)
Rain bands and gusty wind. No name assigned yet.
Tropical Storm (63–88 km/h)
The storm gets a name. Heavy rain and local flooding.
Severe Tropical Storm (89–117 km/h)
Downed trees and power lines, rough seas along the coast.
Typhoon (118–156 km/h)
Roof damage, widespread power outages, storm surge on exposed coasts.
Very Strong Typhoon (157–193 km/h)
Serious damage to buildings, flooding and landslides inland.
Violent Typhoon (194 km/h or higher)
Destruction of weak structures, long-term loss of power and water.
“Super typhoon” is not a JMA class. The US Joint Typhoon Warning Center uses it for 1-minute winds of 241 km/h or higher. The Philippines and Hong Kong use it for 10-minute winds of 185 km/h or higher.
Coastal weather radar reaches a few hundred kilometers offshore. A typhoon appears on RainViewer's radar layer once its rain bands come into that range, usually well before the center makes landfall. Farther out, the storm's track shows its position on the map.
A super typhoon is a very strong typhoon, but the threshold depends on the agency. The US Joint Typhoon Warning Center uses 241 km/h in 1-minute sustained winds. The Philippine weather agency PAGASA and the Hong Kong Observatory use 185 km/h in 10-minute sustained winds.
Typhoon signals are local warning levels, not storm categories. The Philippines uses Tropical Cyclone Wind Signals 1 to 5, and Hong Kong uses signals No. 1, 3, 8, 9, and 10. Each signal describes the wind expected at one place, and the local weather agency issues and lifts every signal.
Typhoons can form in any month of the year. Most form between May and November, and activity peaks in August and September.
Western Pacific typhoons take names from a list of 140 names contributed by 14 countries and territories in the region. The names are used in order, not alphabetically. PAGASA also gives a local name to every storm that enters the Philippine area of responsibility, so one typhoon can carry two names.
The western Pacific holds the largest area of very warm ocean water on Earth. Tropical storms need sea surface temperatures of about 26.5 °C or higher, and much of this region stays above that level for most of the year.
Switch on tropical storm tracks with the icon in the top-right corner of the live radar map. Each typhoon's route appears as a line of colored dots, from where it formed to where it is forecast to go. The RainViewer app for iOS and Android adds 48 hours of radar replay and notifications for each saved location.
