Authorities in Dallas continue recovery efforts Monday after a tornado touched down Sunday night and ripped through parts of the city leaving thousands without power. Nearly 140,000 customers were without power early Monday morning with the threat of more tornadoes in the region.

Police and emergency personnel have been going door to door in different neighborhoods across north and northeast Dallas, evaluating damage and providing help when necessary.

Three people have reportedly been taken to nearby hospitals to be treated for non-critical injuries from the storm. No deaths have been reported.

There are currently about 50,000 customers without power Monday and 100 traffic signals down.

“Considering the path that the storm took, it went across a pretty densely populated part of our city, I think we should consider ourselves very fortunate that we did not lose any lives, no fatalities and no serious injuries in last night's storm,” Mayor Eric Johnson said at a Monday morning press conference.

Johnson said the city's "top priority has been making sure that everyone in our city is safe."

To speed up relief efforts, Dallas County Judge Clay Jenkinson on Monday issued a Local Declaration of Disaster. The declaration could accelerate efforts to clear out debris scattered across the city and get power up sooner.

The storms have also damaged areas in Arkansas, Oklahoma and Missouri. Passengers had to evacuate flights at Memphis International Airport following a tornado warning.
