The only June measurable snow of record at nearby Big Delta, Alaska, was nearly a century ago in 1917. But those seem to be very, very bad readings -- way above freezing, said Alaska-based climatologist Brian Brettschneider.
Your lease is a legal contract that commits you to pay rent for the right to live in the landlord's apartment. Most leases and most jurisdictions require tenants to give notice to their landlords before they vacate the property. On the plus side, the obligation is mutual, which means that your landlord cannot order you to leave without notice.
No notice at all from the landlord is legally or contractually required in this instance. Although it may not required by the lease and is certainly not required by Florida law, we highly recommend that the landlord give a Notice of Non-renewal to the tenant at least 30 days prior to the end of the lease.
