Governor Mary Fallin declares a state of emergency in all 77 Oklahoma counties due to the extreme drought.
The order allows state agencies to make emergency purchases related to disaster relief and preparedness.
It is also a first step toward seeking federal assistance, if needed.
The state of emergency will last for 30 days but can be amended based on conditions on the ground.
Currently, 47 counties have declared burn bans because of the drought and fire danger.
