Tropical Depression 27W (Quinta) Update #2

Tropical Depression 27W (former 93W) continues to intensify as it nears the Eastern Philippines. Both the Joint Typhoon Warning Center and PAGASA have upgraded the LPA into a depression; PAGASA has given 27W a local name of 'Bagyong Quinta'. The system was last located approximately 380km east northeast of Surigao City or about 420km east southeast of Borongan, Eastern Samar. Maximum sustained winds are at 55kph with gusts of up to 75kph. TD 27W is moving west northwestward at 20kph.

As of 5am this morning, PAGASA has raised Public Storm Warning Signal #1 for the islands of Samar and Leyte. Also under Signal #1 are the provinces of Surigao Del Norte, Dinagat Island, Surigao Del Sur, Agusan Provinces, and Camiguin Island. Please note that while we only have Signal #1, it doesn't mean the storm is not destructive anymore. There is a threat for widespread heavy rains across Visayas and parts of Mindanao today. Stay safe!

Latest satellite image shows the significant improvements 27W has made in terms of organization overnight. The convective activity has increased and has also become more consolidated near the low-level center. There is still some shear though and we are noticing that center is still somewhat displaced. Nevertheless, the system will continue to bring the threat of heavy rains for Visayas today.

Using the Doppler Radar from Hinatuan Station, we can see bands of light to moderate rains beginning to move in from the east. Surigao Provinces will see these rains throughout the day today. Farther to the north, bands of light to moderate rains are also beginning to impact Samar and Leyte. These rains will continue throughout the day today and could bring as much as 100mm of rain bringing the possibility for floods and landslides.

Tropical Depression 27W will continue to move west northwestward today, likely making landfall somewhere in Samar later this evening or perhaps early tomorrow morning. Despite this system being a weak tropical depression, do not underestimate it! The heavy precipitation it will bring can bring widespread flooding to many areas. Not only to Samar, Leyte, and Northern Mindanao, but to other parts of Visayas as well.

We'll have another update later today. Have a wonderful and safe Christmas!
