When must controllers broadcast HIWAS alerts?

Explanation:
HIWAS alerts are broadcast to provide timely hazardous weather information to pilots along a route. The key practice is to transmit this information as soon as hazardous weather information is received, so pilots have current data to plan diversions or altitude changes. Waiting for a convenient time, broadcasting only during periods of low traffic, or sending alerts at fixed intervals regardless of new information could leave pilots unaware of dangerous conditions or acting on outdated data. By airing alerts promptly upon receipt, the system ensures pilots receive the critical weather updates they need for safe decision-making.
