You can turn them off. I used to live in NJ and they sent these types of alerts all the time. AMBER alerts in the middle of the night, "Flash Flood" alerts after two drops of rain. It made no sense and I turned them all of off. I live in IL now and I turned them back on because tornados are actually a thing here but also I haven't received any other irrelevant alert.
