Japan: Krosa weakens to severe tropical storm August 12 /update 1

Event

The Japan Meteorological Agency (JMA) warned on Tuesday, August 13, that western and southern parts of the country may see heavy rain and high waves in the coming days before Severe Tropical Storm Krosa makes landfall. Krosa was downgraded from a typhoon to a severe tropical storm on Monday, August 12, but officials forecast it will strengthen again before arriving on either late Wednesday, August 14, or early Thursday, August 15. Kyushu and Shikoku are expected to begin experiencing heavy rainfall on Tuesday. Some areas may receive rainfall totals over 100 cm (39 in) in the coming days. Strong winds and high waves up to 10 m (32 ft) are forecast for Shikoku through Wednesday.

As of 06:45 (local time) on August 13, Krosa is located approximately 600 km (372 mi) southeast of Tanegashima (map here) and is moving northwest at 15 kph (9 mph). The storm has maximum sustained winds of 111 kph (69 mph). Flooding, landslides, mudslides, and strong storm surge are possible in southern and western areas as the storm moves through the region. Power outages and transportation disruptions, including flight delays and road closures, may also occur.

Advice

Individuals in the affected areas are advised to monitor local weather reports, confirm flight reservations, adhere to instructions issued by local authorities, anticipate adverse weather and power and transportation disruptions, and remember that running water can be dangerous - 15 cm (6 in) is enough to knock over an adult - and never drive through flooded streets; floodwater may also contain wastewater and chemical products.
