Tropical Depression Josie, monsoon dump heavy rain
MANILA, Philippines – Tropical Depression Josie accelerated before dawn on Sunday, July 22, while crossing the Luzon Strait and still enhancing the southwest monsoon.
In a bulletin issued 5 am on Sunday, state weather bureau PAGASA said Josie is already 35 kilometers east of Basco, Batanes or 155 kilometers northeast of Calayan, Cagayan, moving northeast at a much faster 35 kilometers per hour (km/h) after its slow pace earlier.
The tropical depression continues to have maximum winds of 60 km/h and gustiness of up to 80 km/h.
Signal number 1 is still raised over:
- northern Cagayan including the Babuyan Group of Islands
Rain and gusty winds are expected in Batanes and the Babuyan Group of Islands due to the tropical depression.
Josie also continues to enhance the southwest monsoon, which is affecting Luzon and the Visayas.
Moderate to heavy monsoon rain is hitting Metro Manila, Central Luzon, the Ilocos Region, the Cordillera Administrative Region, the rest of Cagayan Valley, Oriental Mindoro, Occidental Mindoro, Rizal, Cavite, and Batangas.
At 4 am on Sunday, an orange rainfall warning was raised for Metro Manila, Cavite, and Rizal, which means intense rainfall and flooding is threatening. A yellow rainfall warning was also raised for Bataan, Bulacan, Laguna, Batangas, and northern Quezon, which means heavy rain and possible floods in low-lying areas.
The Visayas and the rest of Luzon will also have occasional rainshowers due to the southwest monsoon.
Areas affected by Josie and the southwest monsoon should be on alert for possible flash floods and landslides. This is especially important as lands in parts of Luzon have already been saturated from the heavy rainfall in the past week. (READ: Monsoon rains increase risk of landslides in Baguio, Benguet)

Based on its latest forecast track, Josie is expected to leave the Philippine Area of Responsibility (PAR) on Monday morning, July 23. That's the day of President Rodrigo Duterte's 3rd State of the Nation Address (SONA).
Aside from Josie, PAGASA is also monitoring a low pressure area (LPA) still outside PAR. Further details on this LPA will be given as soon as they become available.
Josie is the Philippines' 10th tropical cyclone for 2018. The country usually gets an average of 20 tropical cyclones per year. (READ: LIST: PAGASA's names for tropical cyclones in 2018)
Josie comes on the heels of Severe Tropical Storm Inday (Ampil), which left PAR at 1 am on Saturday. Inday did not make landfall in the Philippines, but it enhanced the southwest monsoon.
