REGION
In Region II (Cagayan Valley), floods and
landslides wreaked havoc in the northern
provinces of Cagayan and Isabela on 13
November due to the rains brought by
Vamco (Ulysses) and previous tropical
cyclones and depressions. Local
authorities called it the worst in the region
in four decades.

PEOPLE
AFFECTED
The already swollen Cagayan
River in northern Luzon quickly
rose and inundated low-lying
communities when authorities
released water from Magat
Dam, one of the largest in the
country, to prevent the dam
from reaching its critical
spilling level. About 3,700
rescue personnel from
government and private groups
were deployed over the
weekend and rescued at least
83,600 people from up to
15-foot deep floods. Rescue
operations are still ongoing as
the waters are slow to recede,
with at least 50 villages
remaining isolated.
