Tropical Storm Conson is forecast to bring flooding rains to Vietnam this weekend while Super Typhoon Chanthu is expected to bring damaging winds and extremely heavy rainfall to Taiwan this weekend.
The super typhoon is passing just to the east and north of Luzon in the Philippines early Saturday morning, bringing with it heavy rainfall, severe winds, and coastal inundation.
Portions of Luzon can expect torrential rainfall, typhoon-force winds of 171 to 220 kph, and a storm surge of 1 to 2 meters through Saturday morning as the typhoon tracks to the north.
Throughout the day on Saturday, Chanthu is forecast to track north of Luzon and toward Taiwan while weakening some. The typhoon is forecast to have sustained winds of around 220 kph (135 mph) prior to impacting Taiwan Saturday night into Sunday.
Weather conditions are expected to greatly diminish across Taiwan on Saturday as the storm approaches the southern coast. The island can expect widespread heavy rain of 200 to 300 mm with isolated totals of over 300 mm possible, storm surge, and destructive winds.
Speaking to Taiwan’s state-run Central News Agency on Thursday, Central Weather Bureau forecaster Wu Wan-hua said she expected to see torrential rain across the southern part of the island.
This amount of extreme rainfall could lead to flash flooding and mudslides in Taiwan’s high terrain.
As Chanthu tracks along the east coast of Taiwan, the land interaction could weaken the system even further, however, the storm is expected to maintain winds of above 180 kph (111 mph) through the weekend. These wind speeds are equivalent to a major Atlantic hurricane (Category 3 or higher).
The official forecast track has the system weakening as it tracks north toward China into early next week. Chanthu could stall just off the coast of Shanghai by Monday or Tuesday, which would bring heavy rain to this region as well.
