Tropical Storm Watch Issued for Slidell: Prepare for Hazardous Wind & Surge

A Tropical Storm Watch has been issued for Slidell in Southeast St. Tammany, effective immediately from the National Weather Service in New Orleans, LA, as of October 7 at 3:54 PM CDT. Residents should prioritize preparations for hazardous wind and life-threatening storm surge.

Wind speeds are forecast between 15-25 mph, with gusts up to 40 mph. The NWS advises planning for tropical storm force winds (39-57 mph) and beginning efforts to protect property. Complete all preparations before winds become hazardous. Potential impacts include damage to lightweight structures, broken tree limbs, and scattered power outages. Hazardous driving conditions on bridges are also possible.

A life-threatening storm surge of 3-5 feet above ground is possible from Friday morning until Saturday morning. Residents in surge-prone areas should assemble disaster supplies and know their evacuation routes. Leave immediately if evacuation orders are issued, as failure to do so could result in loss of life. Significant impacts are possible, including inundation and damage to buildings near Lake Pontchartrain and the Rigolets.

Rainfall is expected to be 1-3 inches, with localized higher amounts, presenting little to no flood risk. Tornadoes are not expected. For more information, visit gohsep.la.gov/emergency. This watch is set to expire on October 8, 2026, at 12:00 AM UTC.
