After sweeping over The main island of Luzon in the PhilippinesTrami left large areas submerged under floodwaters, hampering rescue and relief operations as Manila braces for the impact of Typhoon Kong-Rey.

The storm hit the Philippines on Thursday, causing floods and landslides that killed 90 by Sunday, up from 46 reported on Friday, the disaster agency said.

Ariel Nepomuceno, head of the Office of Civil Defense, said many of these reported deaths are still being validated to confirm that the cause of death is directly related to the storm.

Food, water, hygiene and medical supplies are sufficient, however, extensive flooding has hampered relief efforts, with many areas only accessible by boat, Nepomuceno said.

Trami, with wind speeds of up to 88 km/h, reached Hue and Danang. Maximum wind speeds have since dropped to 74 km/h.

The storm forced four airports in central Vietnam to close temporarily, according to the Civil Aviation Authority of Vietnam. Among them, Danang City International Airport will be closed from 6:00 a.m. on Sunday until 4:00 a.m. on Monday.

State media reports said Trami’s strong winds toppled trees and billboards in Danang.

Last month, Typhoon Yagi and the floods it triggered killed more than 300 people and caused more than $3.3 billion in property damage in northern Vietnam.
