2230 UTC September 28, 2011 Typhoon Nesat Update

Typhoon Nesat is now nearing Hainan and could make landfall in that province later tonight. The storm was last located approximately 380km south southeast of Hong Kong or about 290km east southeast of Haikou in Hainan. Nesat remains a Cat 1 typhoon with sustained winds of 120kph gusting to 165kph. It is moving west northwestward at 20kph.

As I mentioned above, this storm is expected to make landfall later tonight in the northeastern coast of Hainan, about 50km east of Haikou. It will then track across the northern portion of the island-province, bringing heavy rain and strong winds to even the Leizhou Peninsula in Guangdong Province.

Latest radar image out of Hainan is already showing widespread light to moderate rains from the outer and inner bands of Nesat. This will continue throughout today and into the night. Expect rainfall amounts of 250mm or more for the next 24 hours.

Even Hong Kong is reporting winds of tropical storm strength. The region has also seen squally showers for the past 6 hours. Stormy conditions there will continue today but should die down by tonight.

Tropical Storm Nalgae, on the other hand, has already entered the Philippine Area of Responsibility. It was last located approximately 1,500km east northeast of Manila and is moving westward at 10kph. Nalgae has strengthened and now has maximum sustained winds of 100kph gusting to 130kph.

It is still forecast to approach the Extreme Northern Philippines by this weekend as a potential Category 2 typhoon.

Typhoon Nesat (Pedring) , Tropical Storm Nalgae 28 SEP 2011 11UTC

Typhoon Nesat continues to move towards the Northwest bringing the potentiol for flooding in Vietnam and South East China. This area has seen an immense amount of rain this past month and with this Typhoon gearing up to make landfall the flooding will only get worst.

Mean while the Philippines prepare for yet another tropical system approaching the islands from the West.  Tropical Storm Nalgae is still gaining intensity and is expected to clip the Northern coast of Luzon as a typhoon by the early part of the next week.

For complete coverage on both of these systems watch update above and also Pat’s most recent update below.

09 UTC September 28, 2011 TY Nesat | TS Nalgae Video Update

This is our latest video update on Typhoon Nesat and Tropical Storm Nalgae. Nesat has finally exited the Philippine Area of Responsibility. All signal warnings have finally been lowered by PAGASA. Conditions should improve now and latest news actually show receding flood waters in Manila Bay, CAMANAVA area, and Marikina River.

Nesat will continue moving west northwestward and could approach Hainan by Friday as a strong Cat 1 Typhoon.

Tropical Storm Nalgae, on the other hand, should enter the PAR tomorrow. Forecasts show it could brush extreme Northern Luzon by Sunday. It could intensify into a typhoon as well. Video Update

Typhoon Nesat Brought Heavy Rainfall to Luzon while Nalgae heads towards the region.

Typhoon Nesat brought a tremendous amount of rainfall across Luzon as it passed on 27th. Over 435mm (17inches) occurred over a 24 hour period in Subic Bay alone. This caused massive flooding and mudslides in Northern Luzon. To the right 3D view of this large storm prior to landfall. The higher cloudy tops indicate the heavy rainfall areas. While below is this same image from overhead.

These rainbands combined with a continues moist air inflow from the south provided Nesat with a constant flow of moisture allowing it to reach such high totals across the country. This combined with the storm surge observed not only on the East coast but also in Manila Bay made this storm especially dangerous as it crossed the Philippines.

Typhoon Nesat continues to track Northwest towards Hainan while newly developed Nalgae bears down on Luzon arriving by this weekend. A full video update will be posted this afternoon on these two systems. Please check the most recent update (below) for the current analysis and tracks.
