SAN DIEGO — A tornado warning was issued by the National Weather Service in two mountain neighborhoods Sunday as Tropical Storm Hilary continues its northward trek.

The tornado warning was issued at 3:39 p.m. for the mountain communities, Alpine and Descanso. The warning was lifted at 4 p.m.

According to a tweet from NWS, radar had indicated rotation and a possible tornado near these communities, but there have since been no reports of a tornado formation.

This comes as Hilary continues to move northward. The center of the storm is anticipated to cross over San Diego County sometime before 6 p.m., likely bringing heavier rain and winds to the region.

Flash flood warnings have been issued for several parts of eastern San Diego County, mostly in the mountain and desert communities.
