There's a mad rush on bottled water in Philadelphia this afternoon. And the photos from grocery stores are showing those insane lines.

This, of course, comes after the city issued a bottled water advisory (just before 1 pm on Sunday). Warning customers that they "may" wish to switch to bottled water for cooking and drinking after 2 pm on Sunday. Click here for the latest info on the city's water advisory.

Immediately following that alert, grocery stores across the city started reporting long lines as bottled water become the hottest product in town.

The rush started quickly following a cell phone alert, which was sent to cell phones across the city advising customers to avoid "tap water" and it said that the city recommended using bottled water as of 2 pm on Sunday (until further notice).

Store officials told CNN that even when they are able to restock their shelves with water they will put purchasing limits on the product for the duration of the advisory. They're expected to limited purchases of cases of bottled water to three per customer, they told

It's unclear when the city will lift the advisory.
