MANILA, Philippines (UPDATED) – The low pressure area (LPA) inside the Philippine Area of Responsibility (PAR) became a tropical depression at 8 pm on Saturday, August 3. It has been given the local name Hanna.

In a bulletin issued 11 pm on Saturday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Tropical Depression Hanna is 940 kilometers east northeast of Virac, Catanduanes, or 1,190 kilometers east of Infanta, Quezon.

It is moving northwest at a slow 10 kilometers per hour (km/h).

The tropical depression has maximum winds of 55 km/h and gustiness of up to 70 km/h. It might intensify into a tropical storm while inside PAR, and then into a severe tropical storm just before exiting PAR.

There are no areas under tropical cyclone wind signals, since Hanna is far from land. It is also not expected to make landfall in any part of the country, only staying near the PAR boundary.

But the tropical depression is enhancing the southwest monsoon or hanging habagat, which is affecting Luzon and Western Visayas.

Below is the expected rainfall from the enhanced southwest monsoon in the next 3 days.
