A private forecasting company took what was intended to be a routine National Weather Service test message and sent it to Southeast Texas subscribers' phones as an official tsunami warning Tuesday morning, the latest in a spate of false alarms since last month. AccuWeather blamed the National Weather Service for the false alarm, saying the government weather agency "miscoded" a test message as a real warning. The National Tsunami Warning Center sent the test message around 7:30 a.m.
