No, it is not uncommon for "rain-wrapped" tornadoes to form.
The formation of a tornado is called tornadogenesis.
it was raining & there was a tornado by the hospital he was born in ..
Cumulonimbus
Since a tornado is a severe weather event, the formation of one would be studied in meteorology.
The rotation within a supercell, caused by wind shear, is a key characteristic that can contribute to tornado formation. The updraft in a supercell can tilt this rotating column of air into a vertical position, leading to funnel cloud development and potentially a tornado.
In order to prevent a tornado watch you would need to be able to control the weather, which is impossible.

yes it can cause tornado formation can take time in an area
They can. Rivers are by no means a requirement for tornado formation, but neither do they prevent tornadoes in any way. A number of tornadoes, for example, have crossed the Mississippi river.
It varies but most often it stops raining a few minutes beforehand. A break in the clouds may be seen, a sign of a downdraft that helps the tornado form. A number of tornado survivors recall it being unusually quite just before the tornado hits.
Yes, tornadoes can occur during heavy rain. These types of tornadoes are known as "rain-wrapped," where the tornado is obscured by the rain and can be harder to see or detect. It is important to stay alert and take cover during severe weather conditions, even if it is raining.
The three steps of a tornado are formation, maturity, and dissipation. During the formation stage, a rotating column of air develops. In the maturity stage, the tornado reaches its maximum intensity, causing the most damage. Finally, during the dissipation stage, the tornado weakens and eventually ceases to exist.
