Narrative:

Amr tower cleared our aircraft for left 45 degree entry for left traffic runway 25. Upon entry into the traffic pattern; upwind traffic for runway 25 turned early left crossswind. This action resulted in a traffic conflict causing both pilots to take immediate action to avoid a traffic conflict. Had the aircraft not turned an early crosswind; spacing would not have been an issue.
