Philippines - May 12th, 2009

Within a week’s time, the northern Philippines were hit by two tropical cyclones, Kujira (01W) and Chan Hom (02W), that left behind more than 42 inches of rainfall to various areas, states NASA.

The image focuses on part of the island of Luzon. Manila, the capital of the Philippines, is located on Manila Bay (bottom), near the green Laguna de Bay Lake (bottom right).

The rivers in the image are brown from sediments dredged up by the heavy rainfall. These sediments can be seen flowing from rivermouths along the coastline, particularly in Manila Bay. To the north, the waters of the Gulf of Lingayen (top left) are clearer.

The storms displaced more than 400,000 people, the vast majority of whom have yet to return home, the National Disaster Coordinating Council (NDCC) reported.

The heavy rains and landslides from the latest tropical cyclone, Chan Hom, killed 43 people after making landfall on May 7th.

It also displaced more than 161,020 people in 51 towns, six cities and 11 provinces in Luzon, the country’s largest island.

Typhoon Kujira, which made landfall on May 2nd, caused 33 deaths and displaced 246,170, according to the NDCC.

The country’s Defence Secretary stated that many casualities occurred, despite early warnings about the typhoons, because many people in coastal areas did not have anywhere to go and tried simply to reinforce their wooden homes.

The state weather bureau said the storms, as well as a tropical depression that proceeded them, ushered in the early arrival of the annual typhoon season, which kills tens of thousands and causes widespread damage. About 20 typhoons strike the Philippines every year.

TS 01W

Kujira (01W) has been downgraded from typhoon to tropical storm status.

The system, which is located approximately 150 nm east-northeast of Iwo-To, Japan, has tracked north-northeastward at 19 knots over the past six hours. Maximum significant wave height is 21 feet.

TS 01W has rapidly lost its vertical organization and is beginning to take on frontal characteristics, indicative of an extratropical system.

With a complete shearing of convection from the low level circulation center (LLCC) and induction of dry mid-latitude air into the LLCC, Kujira is expected to fully transition to an extratropical system within the next 12 hours.

Typhoon 01W

Typhoon 01W (Kujira), located approximately 200 nautical miles south-southwest of Iwo-To, Japan has tracked northeastward at 18 knots over the past six hours. Maximum significant wave height is 22 feet.

Animated water vapor imagery indicates the system continues to maintain good poleward outflow even as it gets eroded on the southwestern quadrant by strong vertical wind shear. This has helped the system maintain its current intensity.

Typhoon Kujira is tracking along the northwest periphery of the subtropical ridge to the southeast. This motion is accelerated by strong winds associated with a mid-latitude trough digging into the East China Sea.

TY 01W is expected to continue its rapid ascent into northern and cooler latitudes, weaken, and become extratropical by TAU 36.

Chan-Hom (02W) Hits Northern Philippines

TS 02W

Chan-Hom (02W) has been downgraded from a typhoon to a tropical storm. It is now located approximately 275 nautical miles northeast of Manila, Philippines, after tracking east-northeastward at 14 knots over the past six hours. Maximum significant wave height is 10 feet.

Before losing strength, Chan-Hom pummelled the northern Philippines, hitting the northern province of Pangasinan late Thursday with maximum winds of 150 kilometres per hour and gusts of up to 185 kph.

Aat least five people were killed in landslides, by drowning and in other accidents, reported disaster relief officials, and others were injured or have been reported missing. The typhoon also caused blackouts and damage to buildings.

Chan-Hom struck the Philippines a few days after typhoon Kujira battered eastern provinces, killing 27 people and damaging more than 9 million dollars worth of crops, livestock and fisheries.

According to the Weather Bureau, Chan-Hom weakened as it made landfall and continued to move north-east at 15 kph. Its maximum winds dropped to 95 kph and gusts of up to 120 kph.

Recent animated multispectral imagery shows a poorly organized low level circulation center (LLCC) with deep convection sheared towards the East with a strong poleward outflow channel. An AMSU-B image shows a well defined LLCC with deep convective banding far to the East of the center.

Upper level analysis indicates the system is in an area of moderate to high vertical wind shear and to the north of the upper-level subtropical ridge axis. Chan-Hom is currently under the steering influence of a low- to mid-level near-equatorial ridge to the Southeast.

The system is expected to come under the influence of a low-level midlatitude ridge to the northeast after TAU 24. The system will then start to track to the north under the new influence and is expected to be out of the Philippines by Sunday.
