Do tornadoes stop at rivers

Answer 1

Tornadoes don't have a particularly significant influence. When tornadoes remove vegetation it may increase runoff and erosion near rives, increasing the amount of water and sediment that enters the river, but this is probably a small contribution. Tornadoes that cross rivers may suck unfortunate fish and other aquatic animals into the air as well. A tornado in Minnesota in 1939 was reported to have momentarily sucked the Mississippi river dry. This, however, was likely an exaggeration.

Answer 2

Houses are often damage or destroyed by tornadoes. The extent of the damage depends on the strength of the tornado and the quality of construction of the house.

With EF0 damage a house may lose shingles and have siding peeled, gutters, and awnings peeled away. A few windows may break. Even in such a weak tornado, some houses may be partially destroyed by falling trees.

With EF1 damage a well built house will suffer severe roof, and siding, and often chimney damage. Broken windows are common. Porches and garages are likely to collapse. In a poorly built house the roof may be completely torn off, and/or an exterior wall may collapse.

With EF2 damage, a well-built house is likely to lose all of most of its roof, but most walls will remain standing. Walls will likely collapse in poorly built houses. Poorly anchored houses may shift off their foundations.

With EF3 damage the walls will collapse or be torn away in well built houses. Sometimes only a few interior walls may be left standing. Poorly built houses may be completely leveled. Improperly anchored houses may be blown away.

With EF4 damage, well built houses will be completely leveled. Houses that are not well built may be blown away. With high-end EF4 damage, all but the strongest houses are likely to be swept away.

With EF5 damage even the sturdiest houses will be swept away, leaving behind empty foundations.

Answer 3

They can remove vegetation which may increase run-off and erosion. This may lead to a more significant amount of sediment in the river.

Answer 4

No, bodies of water cannot stop a tornado.

Answer 5

Tornadoes do not have any significant effect on water sources.
