Tropical Depression Jangmi (Seniang) Update #5 (FINAL)

Issued (04 UTC) 12pm PhT 123114
______________________________

Jangmi (Bagyong Seniang) has weakened to a Tropical Depression as it struggles to maintain intensity across the Sulu Sea. The system was last located approximately 220km northwest of Zamboanga City or about 275km southeast of Puerto Princesa. Maximum sustained winds are at 55kph with gusts of up to 75kph. TD Jangmi is moving southward at 10kph.

As of 11am this morning, PAGASA has raised Public Storm Warning Signal # 1 for Palawan. All other signal warnings have now been lowered.

Latest satellite image shows convection is severely lacking as the circulation center is left exposed due to the strong wind shear in the region. Furthermore, Jangmi continues to display weakening trends this morning which could lead to a total dissipation in the next 24 hours.

Tropical Depression Jangmi will continue moving slowly southward across the Sulu Sea. It could totally dissipate in the next 24 to 48 hours as weather conditions are hostile for cyclone development. Residual rains will continue across parts of Visayas but should taper off in the next few days.

This is our final update for Tropical Depression Jangmi. We'll continue to watch this area for possible redevelopment. Have a wonderful and safe New Year!

Tropical Storm Jangmi (Bagyong Seniang) is now moving into the Sulu Sea although rains continue across much of Visayas. The system was last located approximately 120km southwest of Iloilo City. Maximum sustained winds are at 75kph with gusts of up to 95kph. TS Jangmi is moving westward at 20kph.

As of 11am this morning, PAGASA has raised Public Storm Warning Signal #2 for Negros Occidental, Negros Oriental, Guimaras, Southern Cebu, Southern Antique, and Southern Iloilo. Signal #1 for Palawan, Calamian Group of Islands, Cuyo Island, Aklan, Capiz, Rest of Antiquie, Rest of Iloilo, Rest of Cebu, Bohol, and Siquijor.

Latest satellite image shows Jangmi is not looking as organized as it did yesterday. The central convection is less consolidated and the low-level center is partially sheared from the main convection. Nevertheless, widespread heavy rains continue across parts of Visayas especially across the island of Panay. Even parts of Samar and the Bicol Region are seeing scattered rains today. These adverse weather conditions will continue through the evening hours but should taper off by tomorrow as it already did in Mindanao today.

Forecast Track (NOT OFFICIAL!)

Tropical Storm Jangmi will continue moving across the Sulu Sea today and will move into Palawan by tonight. The center is forecast to pass near the city of Puerto Princesa and will bring widespread rains across the region. Jangmi should move into the South China Sea (West Philippine Sea) by tomorrow and exit the Philippine Area of Responsibility by Thursday.

We'll have another update later tonight.

TD 23W (Bagyong Seniang) has intensified into a Tropical Storm this morning and could make landfall in the next few hours. The storm center was last located approximately 65km southeast of Tandag City or about 160km southeast of Surigao City. Maximum sustained winds are up to 65kph with gusts of up to 85kph. Tropical Storm 23W is moving west northwestward at 10kph.

As of 5am this morning, PAGASA has raised Public Storm Warning Signal #2 for Bohol, Siquijor, Surigao del Sur, Surigao del Norte, Siargao Island, Agusan del Norte, Agusan del Sur, Misamis Oriental, and Camiguin.

Signal #1 for Leyte, Southern Leyte, Camotes Island, Cebu, Negros Oriental, Negros Occidental, Dinagat Province, Compostela Valley, Northern part of Davao Oriental, Davao del Norte, Bukidnon, Lanao del Norte, Misamis Occidental, and Zamboanga del Norte.

Latest satellite image shows strong convective activity in and around the low-level circulation center. Banding has improved and the overall organization of the storm has become more consolidated overnight. Due to the proximity of land, we don't expect any significant intensification although Seniang will likely keep its tropical storm intensity as it makes landfall later this morning.

Radar Image from PAGASA

Latest radar image from Hinatuan courtesy of PAGASA shows bands of light to moderate rains, with pockets of heavy rains, continuing to overspread Mindanao. Many areas have already received more than 100mm of rain and some areas have even reported receiving more than 200mm of rain in the past 36 hours. Unfortunately, rains will continue for the next 48 hours. We expect an additional 100 to 200mm of rain which will increase the likelihood of flash floods and landslides in storm-prone areas.

We urge everyone to please continue closely monitoring the developments of this storm. If you live in low-lying areas and near bodies of water, please coordinate with your local officials for possible evacuation.

We'll have another update later today. Stay safe!

Latest satellite image shows convective activity continuing to build and become more organized. The low-level circulation continues to tighten as the system tries to consolidate just east of Mindanao. Bands of light to moderate rains have already been impacting parts of Visayas and Mindanao since last night. We expect up to 200mm of rain to fall in the next 24 hours increasing the likelihood of flash floods and landslides.

Forecast Track (NOT OFFICIAL!)

 
Tropical Depression Seniang will continue moving west northwestward and will likely make landfall in Surigao del Sur by early tomorrow morning. It will cross into Visayas and will bring widespread rains across the region over the next 2 to 3 days. Intensification will be limited due to land interaction. However, torrential rains will still bring dangerous weather conditions across many areas in Southern Philippines.

We'll have another update later tonight.

Latest satellite image shows bursts of convection surrounding the circulation center of TD 99W. The system is still in the early stages of development and will continue to slowly consolidate in the next 24 hours. Bands of light to moderate rains are beginning to move into parts of Visayas and Eastern Mindanao. We expect conditions in the region to become rainier later this afternoon.

Tropical Depression 99W (Seniang) will continue to slowly intensify today and could become a Tropical Storm in the next 48 hours. It is forecast to move west northwestward and could move towards Northern Mindanao by tomorrow. Widespread rains should be expected across Mindanao and even into Visayas in the coming days. Residents in the region are advised to closely monitor the storm's development and as always, heed the warnings of the local officials.

We'll have another update later today. Stay safe!
