Tropical Depression Zoraida forming southeast of the Philippines, may hamper recovery efforts

JMA and PAGASA are currently warning on Tropical Depression Zoraida, about 300 km south of Palau.  Models project this system to slowly develop over the next couple of days before impacting the Caraga region of Mindanao as well as the Visayas.  While the forecast intensity is nothing compared to Yolanda, heavy rainfall and gusty winds are expected to hamper recovery efforts from both Yolanda and the Bohol earthquake.

One thing slowing the development of this system is the low latitude at which it formed.  Currently just south of 5 °N, Coriolis–an effect caused by the rotation of the Earth and help increase the spin of developing low pressure areas–is very limited and is hindering rapid development.  However, ocean waters and atmospheric conditions remain favorable for development.  Therefore, the consensus is a tropical storm to impact the central Philippines.  Although a tropical storm, those winds can further devastate impaired infrastructure in this region.

If this system is upgraded by JMA to a tropical storm, it would received the North Korean name “Podul” meaning willow tree.

We’ll continue to monitor the progress on Zoraida.  Stay tuned…

Typhoon Haiyan (Bagyong Yolanda) Afternoon Update | November 10, 2013

Typhoon Haiyan is currently affecting Hainan Island and continues to move towards Northern Vietnam. The storm center was last located approximately 230km southwest of Haikou, Hainan or about 400km southeast of Hanoi, Vietnam. Latest warning from JMA shows the winds have decreased slightly with sustained to 150kph and gusts of up to 205kph. Typhoon Haiyan is currently moving northwestward at 30kph.

Latest radar image from China Meteorological Administration shows bands of light to moderate rains impacting Hainan Island and parts of Guangxi and Guangdong provinces. As much as 300mm of rain has already been recorded in many places bringing flooding. Winds of up to 140kph were also recorded in the city of Sanya in Hainan Island causing some damage to structures.

Typhoon Haiyan will continue moving northwestward and could make landfall in Northern Vietnam later tonight. It will pass near Hanoi and should rapidly weaken as it moves further inland. The threat of heavy rain, strong winds, and storm surge will remain through tomorrow. Haiyan will then turn northward into Guangxi Province of China.

For more details on Haiyan please watch our Video Update below:

We also give an update on the situation in the Philippines and the first images out of Guiuan, Eastern Samar showing the destruction in that town. We are also updating viewers on the possible storm that could impact the Philippines this week. If it does form, PAGASA will give the name Bagyong Zoraida and could bring rains for Visayas.

Stay safe!

Typhoon Haiyan (Yolanda) Afternoon Video Update | November 9, 2013

Typhoon Haiyan (Yolanda) continues to weaken as it finally exits the Philippine Area of Responsibility. The system is now moving across the South China Sea with winds of 165kph and gusts of up to 240kph according to the Japan Meteorological Agency. This is also the first full day that allowed government officials and rescue teams to assess the damage out in the Philippines. We continue to get reports, images, and videos of widespread devastation in many islands especially in Samar and Leyte.

Please watch our video below for more in-depth discussion on the damage reports so far:

If you have your own images and videos, please feel free to share them to us.

jma forecast

Typhoon Haiyan will now be moving towards Vietnam and the latest track from JMA above takes the center of Haiyan towards Northern Vietnam, near the city of Hanoi  by Monday morning. The Red River Delta region is home to nearly 20 million people living in low-lying flat lands that will be susceptible to flooding and storm surge once the storm hits. Even parts of Laos and Southwestern China (Hainan Island) could see serious stormy conditions.

Meanwhile, while we really do not want to induce panic to everyone, we are watching a cluster of thunderstorms thousands of kilometers away from the Philippines. Some computer models develop this disturbance into a tropical storm that could affect the Philippines by next week. Please note that all this is uncertain and that we’ll keep you updated on the latest.

Stay safe!

Friday evening update on Typhoon Haiyan / Yolanda battering the Philippines

Typhoon Haiyan / Yolanda continues to batter the central Philippines tonight.  At 5 p.m. PhST, the center of Typhoon Haiyan was positioned about 110 km south-southeast of San Jose, Occidental Mindoro, or about 165 km east-southeast of Coron, Palawan.  JMA reported the central winds at 195 km/h, gusting to 280 km/h (105G150 kt) while JTWC reported 270 km/h gusting to 325 km/h (145G175 kt), which is the equivalent of a category 5 typhoon on the Saffir-Simpson Hurricane Scale used in the Atlantic.

Public Storm Warning Signals remain posted throughout the central Philippines, to include Signal 4 for extreme northern Palawan, Calamian Islands, southern Occidental Mindoro, southern Oriental Mindoro, Aklan, Capiz, Antique, Iloilo, and Guimaras.

Meanwhile, Haiyan continues to pose an extreme wind threat as well as heavy rain (100-150 mm through tomorrow morning) as well as a threat for flash flooding, landslides, and storm surge.

Meanwhile, those in central and northern Vietnam will be preparing for Haiyan to strike them Sunday afternoon through Monday; those in the wake of the storm will begin the recovery phase.  Reports in the Philippines are already reporting up to four deaths.  Military forces are being dispatched to help in the recovery efforts.
