The closures aim to keep air travellers safe from the typhoon, which could bring heavy rainfall and high winds to central Vietnam. The country is also restricting coastal activities to help limit storm damage.
The CAAV stated that Phu Bai International Airport in Thua Thien-Hue will close from 6 am to 10 pm local time, Dong Hoi Airport in Quang Binh from 6 am to 7 pm, Da Nang International Airport from 6 am to 4 am the following day, and Chu Lai Airport in Quang Nam from 10 am to 10 am the next day.
Vietnam Air Traffic Management has notified flights ahead of these temporary closures, local reports say.
The typhoon is forecasted to bring up to 700 mm of rainfall across areas from Quang Binh to Quang Ngai from October 26 to 28.
Typhoon Trami has already caused significant damage in the Philippines, affecting thousands and leaving at least 76 people dead.
