Chaba to threaten Japan as a strong typhoon this week
Typhoon Chaba will threaten lives and property across the Ryukyu Islands and mainland Japan this week.
Chaba strengthened to the equivalent of a Category 3 hurricane on Sunday, local time. Chaba has the potential to reach Category 4 hurricane strength early this week.
Damaging winds, torrential rain and seas will increase around Chaba's center, posing dangers to shipping interests.
Residents of the Ryukyu Islands and southern mainland Japan need to prepare for the future typhoon to make a direct hit or pass dangerously close during the first half of the week.
The Okinawa and Amami islands are at highest risk of being battered by destructive winds and flooding rainfall from Sunday night into Monday, local time. Seas will become dangerously rough and pound the coastline which may cause flooding, especially north and east of Chaba's center.
If Chaba makes a direct hit on any one of these islands, extensive wind damage and prolonged power outages can result. Wind gusts can reach 160 kph (100 mph). Residents who venture outside during the height of the storm would be at risk of injury or death due to flying debris.
125-250 mm (5-10 inches) of rain may lead to extensive flooding in addition to the damaging wind.
After battering these islands, Chaba is then expected to curve toward mainland Japan or the far northern Ryukyu Islands, still as a strong typhoon.
All residents from Nagasaki, Kagoshima, Hiroshima, Osaka and Tokyo are urged to closely monitor the progress of Chaba.
"The timeframe for mainland Japan remains Tuesday and Wednesday for damaging winds and flooding rain from Chaba with the worst of the wind expected over southern Japan," AccuWeather Meteorologist Brian Thompson said.
Chaba expected to make a landfall in southern Japan on Tuesday, still as a strong typhoon. A track to the northeast will then take the weakening storm across central Japan Tuesday night into Wednesday.
Land interaction and disruptive winds above the surface, known as wind shear, will cause Chaba to weaken as it crosses Japan.
"Despite weakening, heavy rain and gusty winds are possible in Tokyo, especially from late Tuesday night through Wednesday," Thompson said.
Confidence is high that Chaba tracks away from northern Taiwan and eastern China, without bringing impacts to these areas.
However, a new tropical threat may develop in the western Pacific and could bring risks to the northern Philippines, Taiwan and southeastern China during the second half of the week. - accuweather.com
