Tropical storm Erin gathered strength instead of weakening as it passed over Oklahoma and Texas, later joining another storm system that had brought mudslides, floods and seven deaths to Minnesota.
Meanwhile, soaring temperatures in the southeastern states of Tennessee, Georgia and Alabama have been blamed for the deaths at least 25 people in recent weeks.
At least 13 deaths were reported in Memphis, Tennessee and a dozen were reported in Alabama, where 100-year plus heat records are being shattered.
