The JMA reported that Bebinca reached its peak intensity at 00:00 UTC on September 15 with 10-minute sustained winds of 140 km/h (85 mph) and a central pressure of 965 hPa (28.50 inHg), [184] before eventually peaking at Category 1-equivalent intensity on the Saffir-Simpson scale with 1-minute sustained winds of 140 km/h (85 mph).

The Philippines is a typhoon-prone country, with approximately twenty tropical cyclones entering its area of responsibility per year. Locally known generally as bagyo (), [3] typhoons regularly form in the Philippine Sea and less often, in the South China Sea, with the months of June to September being the most active, August being the month with the most activity.
The storm's rainfall also prompted PAGASA to declare the start of the 2020 Philippine rainy season on June 12. [33] Typhoon Goni (Rolly) at peak intensity near Catanduanes on November 1, 2020. July 13–14, 2020: Tropical Depression Carina brought heavy rainfall which led to Tropical Cyclone Signal No. 1 being raised over the Babuyan Islands ...
“Under these conditions, flooding and rain-induced landslides are likely,” the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its 11am local time ...
The PAGASA also noted the formation and gave it the name Egay. On July 23, the system began to intensify rapidly, and achieved typhoon status. Late on July 24, the JTWC classified it as a super typhoon. The next morning the PAGASA did the same thing as on that day it reached its peak of 1 minute sustained winds of 240 km/h (150 mph).
An intensity-duration-frequency curve (IDF curve) is a mathematical function that relates the intensity of an event (e.g. rainfall) with its duration and frequency of occurrence. [1] Frequency is the inverse of the probability of occurrence. These curves are commonly used in hydrology for flood forecasting and civil engineering for urban ...
From the statistics gathered by PAGASA from 1948 to 2004, around 28 storms and/or typhoons per year enter the Philippine Area of Responsibility (PAR) – the designated area assigned to PAGASA to monitor during weather disturbances. Of those that made landfall or crossed the Philippines, the average was nine per year.
