Authorities in Texas so far do not have any confirmation of fatalities from monster Hurricane Harvey, which slammed into the state's Gulf Coast, dumping torrential rains, Governor Greg Abbott said Saturday.

Abbott told reporters that for now, his primary concern remains "dramatic flooding" in his state, and warned residents to be on guard for rapidly rising water.

"We don't have any information right now that we can confirm any fatalities," Abbott said, adding that he was working with local officials and report back later if the situation changed.
