Flash Flood Emergency Declared for Picayune and Nicholson Mississippi as Catastrophic Life-Threatening Flooding Hits With Multiple Roads Flooded
MISSISSIPPI — A Flash Flood Emergency — the most serious flood designation issued by the National Weather Service — is in effect for Picayune and Nicholson, Mississippi, with catastrophic and life-threatening flooding happening right now. Emergency management has confirmed multiple roads are already flooded across the area. This is as serious as it gets. Anyone in the affected zone must move to higher ground immediately and under no circumstances attempt to walk, swim, or drive through floodwaters.
Catastrophic Damage Expected — Particularly Dangerous Situation Declared
The Flash Flood Emergency carries an explicit label of Particularly Dangerous Situation, reserved for only the most extreme and life-threatening flash flooding events. Catastrophic damage is expected across Picayune and Nicholson, with the emergency valid until 12:00 PM CDT Thursday, June 18, 2026.
The radar at 9:10 AM CDT shows an intense and expansive area of extreme rainfall centered directly over Picayune, with deep red and purple returns indicating the heaviest rainfall cores concentrated over the warned area. The emergency polygon is centered over Picayune with extreme rainfall extending across the broader Pearl River County corridor.
Multiple Roads Already Flooded Across Picayune and Nicholson
Emergency management has confirmed that multiple roads across Picayune and Nicholson are already flooded as of this morning. Floodwaters on roadways can be far deeper and faster-moving than they appear, and even a few inches of moving water can knock a person down while two feet of water can carry away most vehicles.
The official guidance is clear and non-negotiable: turn around, don’t drown. Do not attempt to drive through any water-covered roadway under any circumstances.
Move to Higher Ground Right Now — Do Not Wait
For anyone in Picayune, Nicholson, and surrounding Pearl River County communities, the time to act is right now. Do not wait for conditions to worsen before moving to higher ground. Floodwaters can rise with extreme speed during a Flash Flood Emergency, and any delay in moving to safety increases the risk of being trapped.
