Tracking severe storms, flash flooding, tornado threat in the Philly region

The region faces about a 10-inch deficit in rainfall. Three to four inches of rain a month are typical during the winter.

Homeowners are not required to inspect their septic systems until they sell their home, meaning deteriorating systems could go unnoticed.

The notice comes after the state declared a drought warning Wednesday as the region faces record-low rainfall, leading to the driest conditions in the past 120 years.
