Great Danger in Aurora – Typhoon KOPPU/Lando now Cat.4

Weather 2015-10-17

Great Danger in Aurora – Typhoon KOPPU/Lando has now developed an eye and has been upgraded to Category 4. PAGASA has hoisted Storm SIgnal #4 over Aurora. The cyclones forward speed is very low, 10 to 15 km/h.

The situation in Aurora province is getting extremely dangerous. Wind speeds of 210 to 250 km/h are to be expected tonight. Such winds will destroy lightly built houses and knock down many trees. On the coast a big storm surge is expected to be as high as 14 meters (46 feet). This is the height of a 4 storeys building.

At 7:33 p.m. a plane from the United Nations /ETH628) coming from Bangkok has landed in Manila. We do not yet know what their mission will be. Already first relief goods?

Typhoon KOPPU/Lando track forecast

Weather 2015-10-17 JMA

During the last 3 hours the cyclone has slightly changed its track to northwest.

The Big Danger

Typhoon KOPPU/Lando started to interact with his follower, Typhoon CHAMPI. Although CHAMPI will not hit the Philippines as is already turning slightly northwest, it influences the forward speed of KOPPU/Lando. High Pressure Areas (HPA) over Korea and Japan also slow down the northward movement. The result is that Typhoon KOPPU/Lando might hover over northern Luzon until Wednesday next week.

With its diameter of about 850 km, Typhoon KOPPU/Lando will continue to bring in big masses of water and spill it over northern Luzon. Even if wind speeds will decrease when the storm is over land, the heavy rains will trigger floods and landslides.

Philippine President Benigno Aquino III warned that Typhoon KOPPU/Lando could be uniquely destructive because it would bring intense rain over a long period of time. Well, that’s politics.
