*SOURCE: PAGASA

Philippines - Typhoon Koppu/ Lando is now a category 3 typhoon as of October 18, 2015 at 4:00 am local time. Packing winds of 175 kph near the center and gustiness up to 210 kph and forecast to move west at 3 kph per hour. It is the 12th typhoon to hit the Philippines.

Why a strange typhoon? Typhoon Lando with its international name Koppu interacts with another typhoon in the pacific, Typhoon Champi this interactions is known as a fujiwara effect thus making the movement of TY Lando slows. Also there is a High Pressure in the west Philippines Sea affecting the movement of TY Lando  and this Typhoon is projected to linger in the Northern and Central Luzon for 3 more days.

Because of its slow movement residents in the Northern and Central Luzon including Mertro Manila should monitor the amount of rains brought by TY Lando. Torrential rain is expected to cause flood in that part of  Luzon.
