The latest storm information from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that at 3:00 a.m. on July 2, the center of the low pressure was at about 16.9 degrees north latitude, 123.9 degrees east longitude, about 200km east-northeast of Casiguran (Aurora), and 235km east of Echague ( Isabela).
This low pressure is located in the Philippine Forecast Area (PAR) and is likely to develop into a tropical depression today (July 2).
Due to the distance close to land, a level 1 strong wind warning may be issued along the coastal provinces of Northeast and Northern Luzon immediately after the low pressure reaches tropical depression level.
Meanwhile, the southwest monsoon continues to affect Central Luzon, Southern Luzon, Visayas and Mindanao, causing widespread heavy rain. The rainfall is forecast to increase sharply in the next 48 hours, especially in the Northern and Central Luzon areas.
There is a high risk of localized flooding, landslides in mountainous areas and overflow in low-lying urban areas.

This system has a clear convective center, is gradually becoming stronger and tends to move slowly northward, affecting the east coast of Luzon (Philippines), Taiwan (China) and Okinawa Island (Japan) in the coming days.
