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 about 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 millimeters with isolated totals of over 300 millimeters possible.

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.

The official forecast 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.

Conson brings flood threat to Vietnam this weekend

The outer bands of the storm are already bringing thunderstorms and gusty winds to the region on Friday and weather conditions will continue to deteriorate across Vietnam on Saturday as the storm approaches the coast.

Although it is a much weaker storm than Super Typhoon Chanthu, Conson is still expected to have sustained winds of 75 kph (45 mph) prior to landfall this weekend.

The Vietnamese government has also ordered vessels to stay in port and prepared evacuation plans, Reuters said, quoting state-run media. As many as 800,000 people in Vietnam's northern provinces could be affected by the storm's arrival -- the fifth to make landfall in the country this year.

Conson is forecast to bring widespread rainfall of 100 to 200 millimeters to the region through Monday with isolated totals above 250 millimeters possible. This amount of rain could lead to flash flooding and mudslides across the mountainous terrain.

Earlier this week, Conson brought heavy rain and gusty winds to the Philippines. The storm traversed the central Philippines Monday afternoon through Wednesday before emerging into the South China Sea early Thursday morning.

As the storm moved west into the South China Sea, all warnings were lifted for Luzon.
