Tisoy is the Philippines’ 20th tropical cyclone for 2019. (READ: LIST: PAGASA’s names for tropical cyclones in 2019)

The country gets an average of 20 tropical cyclones annually. In the earlier part of the year, only 14 to 18 tropical cyclones had been projected since 2019 is an El Niño year.

For the month of December, PAGASA had been expecting 0 to 1 tropical cyclone.

PAGASA declared the start of the rainy season last June 14. – Rappler.com
