Track of TY 15W

Typhoon Megi (15W) is located approximately 350 nm south-southeast of Hong Kong, China. It has tracked northwestward at 3 knots over the past six hours.

Megi has maximum sustained winds of up to 115 knots, with gusts of up to 140 knots. These wind speeds are forecast to intensify over the next 12 hours.

Megi passed over the northern part of the Philippines on Monday, killing at least 10 people, the BBC reports. Officials say the toll could rise; communications links are down and the full extent of damage is not known.

Typhoon Megi was the strongest to hit the Philippines for several years and caused significant damage, tearing the roofs off houses and cutting power. It was a category five super typhoon with winds in excess of 250 km/h (155 mph) when it hit the east coast of north Luzon shortly before noon on Monday.

It has now passed over the main island, Luzon, and is heading towards the southern coast of China. Forecasters predict severe weather there by the weekend. On the southern Chinese island of Hainan, the rain prompted more than 100,000 people to leave their homes over the weekend.

Typhoon Megi could also hit Vietnam, where unrelated floods have swept people away and flooded thousands of homes, killing at least 31 people, with 23 people missing. Flash floods have also hit northern Thailand’s Nakhon Ratchasima province.

Track of TS 07W

Tropical Storm Lionrock (07W), located approximately 215 nm southeast of Hong Kong, has tracked north-northwestward at 07 knots over the past six hours. Maximum significant wave height is 13 feet.

Animated infrared satellite imagery depicts a consolidating low-level circulation center (LLCC) with improved convective banding wrapping into the center. The main image shows the convection on the western side of the system.

Upper-level analysis indicates that vertical wind shear has decreased to 5-10 knots with improved poleward outflow enhanced by a trough over southeast China. The current intensity is based on Dvorak estimates of 35 knots.

Lionrock is forecast to track north-northwestward to northwestward through TAU 48 when it will make landfall. Then, the system should turn westward. It is forecast to intensify to a peak of 55-60 knots and should dissipate over land by TAU 96.

Track of Parma and Melor

In a week that saw Samoa hit by a tsnuami and Indonesia shaken by an earthquake, the Philippines, caught a break: Typhoon Parma (19W) missed the capital of Manila.

Just one week after a hurricane flooded 80 percent of Manila, killing 300 people and displacing at least half a million, the devastated city has been spared a second major storm. Typhoon Parma had threatened to dump even more heavy rains over the city, trigger more landslides, and block relief efforts, reports the CSM.

Though typhoon Parma did strike the island of Luzon, where Manila is located, and kill 16 people, it then bypassed the capital and edged toward the less densely populated north.

Parma was also downgraded to a tropical storm Monday, with winds of 59 mph and gusts of up to 75 mph, according to the Associated Press. The storm is now located approximately 330 nautical miles east-southeast of Hong Kong, has remained quasi-stationary over the past six hours. Maximum significant wave height is 30 feet.

Parma is still expected to cause severe damage, though, dumping heavy rains not just in the northern Philippines but also Taiwan, where 6,000 villagers have been evacuated. Instead of continuing on its path away from the country, it’s predicted to linger over the city of Laoag and surrounding areas until Thursday. That’s because a third typhoon, Melor (to the right in the animated image), churning in the Pacific, is acting “like a magnet” and holding Parma in place, according to Agence France-Presse.

Super Typhoon Melor (20W), on the other hand, is projected to pass over Philippine waters but not hit the mainland. It is now located approximately 500 nautical miles southeast of Okinawa, and has tracked northwestward at 14 knots over the past six hours. Maximum significant wave height is 40 feet.

Hong Kong Island and Kowloon Peninsula – August 3rd, 2009

Hong Kong - July 14th, 2009

Hong Kong is located on China’s south coast, 60 km (37 mi) east of Macau on the opposite side of the Pearl River Delta. It is surrounded by the South China Sea on the east, south, and west, and borders the city of Shenzhen in Guangdong Province to the north over the Sham Chun River.

The territory’s 1,104 km2 (426 sq mi) land area consists primarily of Hong Kong Island, Lantau Island, Kowloon Peninsula and the New Territories as well as some 260 other islands.

A channel with several bays and harbors separates Kowloon Peninsula from Hong Kong Island. Upon opening the full orthorectified image, many ships can be seen navigating this passage, while others are visible in the South China Sea.

As much of Hong Kong’s terrain is hilly to mountainous with steep slopes, less than 25% of the territory’s landmass is developed, and about 40% of the remaining land area is reserved as country parks and nature reserves.

Most of the territory’s urban development exists on Kowloon Peninsula and along the northern edge of Hong Kong Island. These areas appear bright white, lining the strait that separates them.

Tropical Storm 07W (Molave/Isang) Expected to Make Landfall Near Hong Kong This Weekend

Track of TS 07W

Tropical Storm Molave (07W), named Isang in the Philippines, is located approximately 305 nautical miles north-northeast of Manila, Philippines, has tracked northwestward at 10 knots over the past 6 hours. Maximum significant wave height is 14 feet.

TS07W continues tracking along the southwestern periphery of an extension of the subtropical ridge, located to its northeast. Multispectral imagery indicates that the low level circulation center (LLCC) has quickly become organized with tightly curved banding developing toward it.

As Molave tracks to the north of Luzon, the inflow of relatively drier air (apparent in total precipitable water products) has led to a decrease in deep convection on the southeastern periphery. However, this has been offset by increased deep convection on the northern periphery.

Upper level analysis still indicates strong equatorward outflow is present. Sea surface temperatures are favorable for development, and the ocean heat content (OHC) products indicate there is a large region of deep, warm water between Luzon and Taiwan helping to fuel a brief period of rapid development.

High pressure to the north and northeast of 07W will steer the storm into the South China Sea this weekend and will take aim at China. However, the OHC will decrease as TS07W tracks into the northern portion of the South China Sea and, in association with increased vertical wind shear, will begin to weaken. Molave is forecast to make landfall near Hong Kong around TAU 36 and quickly begin to dissipate, with full dissipation by TAU 72.

Before it reaches China, 07W will pass through the Luzon Strait Friday. Despite remaining over water, 07W will impact Luzon Island with locally heavy rains and strong, damaging wind gusts Friday. Rainfall amounts could exceed 5 inches (125 mm) in some areas, resulting in flash flooding and landslides. Wind gusts could be as high as 70 mph (115 kph) during the day as well.
