Perry issued a statement Friday night saying rainstorms that dumped up to 10 inches near Jarrell, Texas, and were expected to continue Saturday were particularly dangerous, CNN reported.
"As rainfall continues, the state is taking precautionary measures in the event assistance is needed ... I urge everyone in the communities impacted by these storms to be extra cautious and pay attention to the changing weather conditions," Perry said.
Perry said as many as four Blackhawk helicopters will be ready to deploy Saturday along the Interstate 35 corridor, which was closed near Jarrelll due to flooding.
Accuweather.com predicted heavy showers and thunderstorms would continue to threaten eastern Texas, southern Arkansas, Louisiana and southern Mississippi with torrential downpours and small hail. The slow-moving storms will linger for several days and produce several inches of rain, forecasters said.
