MANILA, Philippines – Three areas in Luzon were placed under Signal No. 1 late Monday night, July 15, due to Tropical Depression Falcon.

In a bulletin issued 11 pm on Monday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Falcon is already 855 kilometers east of Casiguran, Aurora, or 890 kilometers east of Tuguegarao City, Cagayan.

The tropical depression accelerated further, now moving northwest at a slightly faster 30 kilometers per hour (km/h) from the previous 25 km/h.

Its maximum winds earlier increased from 45 km/h to 55 km/h on Monday afternoon, while its gustiness increased from 60 km/h to 65 km/h. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

Signal No. 1 is now raised over the following:

Cagayan

Batanes

northern part of Isabela (1st and 6th Districts)

This means winds of 30 km/h to 60 km/h are expected in those 3 areas in 36 hours. Residents have lead time of 36 hours to prepare for the effects of the approaching tropical depression.

PAGASA warned that Falcon may intensify into a tropical storm before its possible landfall in Extreme Northern Luzon – the Batanes-Babuyan area – on Wednesday afternoon or evening, July 17.

The tropical depression is also enhancing the southwest monsoon or hanging habagat – another source of rain.

Falcon is expected to leave the Philippine Area of Responsibility on Thursday, July 18.

July - 2 or 3

August - 2 to 4

September - 2 to 4

October - 2 or 3
