Narrative:

Aircraft X arrived at ZZZ1 with a 'slat fail' EICAS message write-up. Maintenance reset and signed off aircraft. I asked maintenance to cycle flaps on ground; and they did successfully. Just after liftoff; the 'slat fail' EICAS message annunciated; with slats frozen at position 3. QRH procedures were accomplished and reduced airspeed and altitudes were complied with. Contacted dispatch and requested a diversion field because of time/fuel considerations to our destination of ZZZ2 and ZZZ1 having marginal category I conditions (1/4 VV1 fg). Dispatch assigned ZZZ3 as the diversion destination. We completed the QRH procedures; briefed the flight attendants and passengers and landed normally in ZZZ3. Mechanical failure of a slat position sensing component.
