MANILA (2nd UPDATE) - Auring weakened into a tropical depression late Sunday as it continued to move towards the area of Dinagat Islands, Eastern Samar, and Leyte for its initial landfall, the state weather bureau said.
The country's first storm this year was last estimated 195 kilometers east of Maasin City, Southern Leyte as of 4 a.m. Monday, PAGASA said in its 5 a.m. bulletin.
It was packing maximum winds of 45 km per hour (kph) near the center and gusts of up to 55 kph while moving west northwest at 15 kph, it added.
Auring was forecast to hit land in the area of Dinagat Islands-Eastern Samar (southern portion including Homonhon Island)-Leyte in the next 6 to 12 hours, according to PAGASA.
PAGASA also said the tropical cyclone may further weaken before its landfall due to persistent high vertical wind shear associated with the surge of the northeast monsoon.
"Post-landfall, Auring is forecast to weaken considerably due to significant terrain interaction and the increasing wind shear, leading to deterioration into a remnant low within 24 hours, possibly sooner," the weather bureau said.
On Monday, moderate to heavy rains are expected over Bicol region, Northern Samar, Samar, Eastern Samar, Biliran, Leyte, Marinduque, Romblon, and Quezon. Light to moderate with at times heavy rains over Aurora and the rest of Visayas, Mimaropa, and Calabarzon.
PAGASA warned that scattered flooding, including flash floods, and rain-induced landslides may occur in affected areas during heavy or prolonged rainfall.
"Adjacent or nearby areas may also experience flooding in the absence of such rainfall occurrence due to surface runoff or swelling of river channels," it said.
PAGASA placed the following areas under tropical cyclone wind signal no. 1 where 30 to 60 kph winds in 36 hours were expected to prevail:
