According to storm news, the latest low pressure from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), at 4 am on August 3 (local time), the center of the tropical depression Luis was located about 130 km east-southeast of Casiguran, Aurora province.
The tropical depression is almost standing still, maintaining the strongest wind near the center at 55 km/h, gusting up to 70 km/h.
Storm warning signal No. 1 (TCWS No. 1) was issued in 10 areas in Luzon, including: the central and eastern areas of Cagayan province, Isabela, Quirino, eastern and southern Apayao, eastern Kalinga, eastern Mountain Province, eastern Ifugao, northern Aurora province, Polillo archipelago and northern Camarines Norte province.
According to warnings, areas within the affected area may experience strong winds from 39-61 km/h in the next 36 hours. The level of wind impact is assessed from low to low, but can still affect trees, light structures and outdoor activities.
From now until the afternoon of August 3rd, the provinces of Pangasinan, Cagayan, Isabela, Quirino, Zambales, Tarlac, Nueva Ecija, Bulacan, Aurora and Quezon are forecast to have rainfall from 50-100 mm.
From the afternoon of August 3rd to the afternoon of August 4th, heavy rain with rainfall of 50-100 mm will extend to La Union, Pangasinan, Benguet, Isabela, Quirino, Aurora, Nueva Ecija, Bulacan, Tarlac, Pampanga, Zambales, Bataan, Manila metropolitan area, Cavite, Batangas and Rizal. The Occidental Mindoro area will be mainly affected by the Southwest monsoon with moderate to heavy rain.
From the afternoon of August 4 to the afternoon of August 5, PAGASA forecasts that Zambales, Bataan and Occidental Mindoro are likely to experience heavy to very heavy rain due to the combined impact of monsoons.
PAGASA said that tropical depression Luis is likely to maintain its tropical depression intensity for most of the forecast period before weakening into a residual low pressure area on August 5 and fully integrating into the circulation of Hurricane Dolphin.
Meanwhile, Typhoon Dolphin is currently about 2,850 km east-northeast of Luzon's northernmost point, outside the Philippine Area of Responsibility (PAR). The typhoon has maximum sustained winds of 155 km/h, gusts up to 190 km/h and is moving northwest at a speed of 25 km/h.
PAGASA assessed that Typhoon Dolphin has not directly affected the Philippines and the possibility of entering the Philippine Area of Responsibility is still low.
PAGASA also noted that heavy rain and strong winds may still occur in areas outside the forecast path of the tropical depression Luis. People are advised to continue to monitor weather reports and follow local authorities' instructions to proactively respond.
