Continuous Rain
Continuous rain is rainfall that persists steadily over an extended period without significant breaks, a pattern that raises flood risk even at moderate rain rates due to accumulated volume.
Heavy Rainfall
Heavy rainfall generally refers to rain falling at 7.5 mm per hour or more, the threshold where PAGASA begins issuing color-coded rainfall warnings.
Intense Rainfall
Intense rainfall describes rain falling at a rate significant enough to cause rapid runoff and flooding, generally in the range covered by PAGASA's orange rainfall warning.
Localized Rainfall
Localized rainfall describes rain concentrated in a specific area rather than spread evenly across a region, often tied to individual rainbands or terrain effects.
Rain Rate
Rain rate is the intensity of rainfall measured in millimeters per hour, the figure PAGASA uses to determine which color-coded rainfall warning to issue.
Rainfall
Rainfall is the general term for precipitation falling as rain, measured in millimeters and tracked both as a rate per hour and as total accumulation over a storm's passage.
Rainfall Accumulation
Rainfall accumulation is the total amount of rain that has fallen over a set period, such as 24 hours, distinct from rain rate, which measures intensity at a single point in time.
Rainfall Advisory
A rainfall advisory is a PAGASA notice highlighting expected rain intensity and potential flooding impact, issued using the yellow, orange, and red color-coded warning levels.
