An afternoon line of storms ripped across St. Tammany Parish on Friday, dumping heavy rain, kicking up gusty winds and triggering pockets of localized flooding across parts of the Northshore. Parish officials shared video of the wild weather and its immediate aftermath, with downed limbs and standing water turning neighborhood streets into slow-moving traffic puzzles.
The National Weather Service in New Orleans had already been sounding the alarm for southeast Louisiana on Friday, warning of isolated flash flooding and a marginal severe storm threat, according to the NWS New Orleans/Baton Rouge office. Its hazard graphics highlighted a low end risk for strong winds and tornadoes and cautioned that multiple rounds of heavy rain could lead to street ponding and brief rises on smaller streams.
The Weather Prediction Center also flagged a marginal risk for excessive rainfall over the Lower Mississippi Valley on Friday, with forecast guidance pointing to localized rainfall totals of 1 to 3 inches that can easily aggravate urban and poor drainage flooding, according to the Weather Prediction Center. Forecasters pinned the setup on a stalled frontal boundary teaming up with deep Gulf moisture.
