A Southwest Airlines Boeing 737-8 MAX, registration N8841L performing flight WN-425 from Columbus,OH to Tampa,FL (USA), had been holding enroute due to weather at Tampa before continuing the approach to Tampa. On final approach to Tampa's runway 10, ambient pressure was stated 30.14 in/Hg by tower, the crew was advised of a headwind gain of about 10 knots at low altitude and a "bumpy ride". The aircraft descended below minimum safe height, when tower issued a low altitude alert they levelled off. About 50 seconds after the low altitude alert tower queried whether they were planning to go around, which the crew affirmed. Tower cancelled the approach clearance and instructed a go around. The aircraft initiated a go around from about 370 feet AGL (compensated for local ambient pressure) about 4.2nm before the runway threshold. The aircraft climbed out to safety and diverted to Fort Lauderdale,FL (USA) for a safe landing about 40 minutes later.

The aircraft remained on the ground in Fort Lauderdale for about an hour, then continued to Tampa for a landing without further incident.

ADS-B data suggest the aircraft descended to about 370 feet AGL/MSL, about 150 feet measured to standard pressure (which puts the aircraft 220 feet higher than the transponder suggests due to ambient pressure at 30.14 in/Hg), about 4.2nm before the runway threshold before going around.
