which type of rains are most powerful?

Could you please elaborate?

Rainfall depends on several variables - i.e. type of weather system (e.g. cumulonimbus clouds (very localized), or very large weather systems such as hurricanes/typhoons), relative humidity, temperature, pressure, and variations in these properties.

A rainfall or 1 - 2 inches (2-5 cm) in 1 hr may cause limited flooding, while in a 24 hour period would not be severe. Even with low rainfall amounts like these, persistent rainfall such as 4 or more days of rain can lead to flooding once the ground is saturated with moisture.

On the other hand, I have been in several situations with 10-12 inches (25-30 cm) of rain in 24 hrs and one period with approximately 20 inches (50 cm) of rain in two days. In these cases, substantial flooding over a wide area was the result.

With heavy rains, there is often wind, and some times there are downdrafts (downwinds) or microbursts with wind speeds of 10's of mph (km/h). The wind can be damaging above 40mph (64 km/h). I have been near the ocean where the wind blew the rain at an angle of something like 20-30° from horizontal. In that case, I could not see more than a few feet (2-3 m) in front of my face.

Tornados are associated with storm conditions that cause locally heavy rain.

The most powerful type of rain is typically associated with severe weather events such as thunderstorms, hurricanes, and typhoons. These types of rains are known for their intense downpours, strong winds, and potential for causing significant damage. They are often accompanied by other extreme weather phenomena such as lightning, hail, and tornadoes. These powerful rains can cause flash flooding, landslides, and other dangerous conditions. It is important to take proper precautions and seek shelter during these types of rains to ensure personal safety and minimize property damage.
