Authorities are concerned about the effects of Typhoon Koppu that may last three days, as the weather system is trapped in its movement by another typhoon.
Joho DU1VHY said the HERO Network has also been set up at the request of the National Telecommunication Commission’s Deputy Commissioner.
HERO traffic so far only has one significant report from the province of Aurora where there is an increase in rain and wind velocity.
Typhoon Koppu is expected to track upwards through the centre of Luzon Island. It made landfall early on Sunday and is not expected to leave the archipelago until Tuesday.
The weather forecast is for there to be heavy to intense rainfall and possible storm surges in coastal areas. Due to its interaction with the nearby Typhoon Champi, it may move slowly across the northern end of Luzon, and be almost stationary once it hits.
