Gov. Sam Brownback is urging Kansas residents to remain on guard as severe weather continues in much of the state.

The governor said Thursday that residents should seek cover immediately when tornado warnings are issued.

Numerous tornadoes have touched down in Kansas this week. Most have caused little to no damage, but two businesses and about 20 homes were damaged or destroyed Monday night in the northeastern town of Maryville.

The following night, more tornadoes in northeast Kansas caused scattered damage in Nemaha County, and about 100 cattle were killed when a twister hit Ottawa County north of Salina.

Flash flood warnings were posted for parts of Kansas on Thursday as heavy rain continued to fall.
