Narrative:
During approach to msy runway 10, approach control reported microburst alert on final for opposing runway 28. There was a cell just east of the runway. After switching to tower, they called a microburst alert for departure path runway 10, not for the arrival. Later, they reported other microburst alerts on other parts of the airport, north of the runway a few mi. The end result was I never understood there to be a microburst alert for our arrival path,. But I felt like there was a little too much information. Microburst reports were moving to different locations and the end result was I never understood there to be a microburst report for our runway, but by the time we landed, I wasn't so sure. The copilot felt sure there was not a microburst report for our runway. There was no warning from predictive windshear system and we had no variation in airspeed, smooth conditions and landed without incident.
