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.
To get out of a lease without giving 30 days notice, you either need the mutual consent of the landlord and tenant or there must be a serious breach of the lease. California Civil Code section 1933 allows a landlord and tenant to terminate a lease by mutual consent.
