Medicare entitlement and enrollment decisions may be transmitted through letters delivered
            by the U.S. Postal Service. Beneficiaries may elect to enroll in premium Part A and/or
            Part B by mailing their enrollment decision to SSA.
         
         The severity and duration of extreme weather-related events and other emergencies
            can be difficult to accurately predict, but may strip individuals of their ability
            to carry out day-to-day activities. These events can result in disruptions in mail
            delivery, field office closures due to disruptions in electricity or phone access,
            and operational delays, any of which can prevent individuals from submitting their
            enrollment application in a timely manner.
