Probable cause

The pilot's poor preflight preparation when he failed to recheck weather conditions after he delayed takeoff because of thunderstroms. Also, the pilot's poor inflight decision to land off-airport rather than return to the departure airport.

Analysis

Prior to departure the plt was briefed by fss personnel that thunderstorms existed along the route of flt & advised to wait an hour for movement to the east. The plt did not contact the fss again prior to departure. The flt departed 1 hr 29 minutes later & when north of lake Okeechobee, FL, encountered weather associated with a thunderstorm & with darkness approaching, elected to perform a precautionary landing. During the landing roll, the nose gear collided with a mound of dirt, collapsing it, & both wings collided with trees before the airplane stopped.
