National Weather Service (NWS) offices across the country conduct regular weekly tests of the Emergency Alert System (EAS). All EAS systems are required by law to be tested on a weekly basis. These Required Weekly Tests (RWT) are not required to have audio or visual components, but some may include a brief message explaining test with an end-of-message tone. Some RWTs also identify the counties covered. NWS offices attempt to conduct RWTs at the same time every week, however, they will postpone tests during adverse weather.
