How often? Flooding occurs in the Philippines so many times. I can't tell you exactly but I think it happens for not more than 10 times a year. Last year we experienced Ondoy ( KETSANA ).
Everywhere...its an island

Geographical solutions to flooding can include creating more green spaces to absorb water, implementing sustainable drainage systems (SuDS) to manage runoff, building flood barriers and embankments, and restoring natural watercourses and wetlands to help regulate water flow. These solutions focus on managing water effectively to reduce the risk and impact of flooding in vulnerable areas.
flooding may occur or sometimes flash flooding
Dysentery is one disease that is likely to occur from poor sanitation and flooding.
Severe thunderstorms often occur along cold fronts. These storms can produce damaging winds, large hail, flooding, and sometimes tornadoes.
From July to November.
"Localized" -- Flooding that will occur in smaller areas, just certain local places that usually flood within a fairly limited area. Such as "localized flooding may occur in parts of the state's southeast counties if the rain continues, but no serious widespread flooding will occur in any large areas of the state." The opposite is widespread or regional flooding which covers more area(s) than local.

Flash flooding can occur in the desert after a heavy rain.
Mostly in the autumn
Yes. Tornadoes occur in the Philippines.
