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.
Some landlords will send a courtesy notice 60 days prior to the expiration of a lease to offer tenants an opportunity to renew the lease and to notify tenants of any new lease terms such as a rent increase, but this type of notice is not a legal requirement.
