Si Fly Flight 3275 were found in good condition. Analysis from the crash site concluded that the plane struck tree tops first before impacting terrain. The first impact occurred 15 metres from the top of a ridge, in a rocky mid-mountain area. During the impact, the fuselage and wing disintegrated, the fuel ignited, and an explosion occurred. The French BEA then collected weather data prior to the crash. From Slovenia to Greece and from Italy to Bulgaria, the winds at altitude were very weak from the north. They were sufficient to create a foehn effect under the mountain winds that left the whole coast
Weather forecasting if more than , the larger the change in weather can be expected. If the pressure drop is rapid, a low pressure system is approaching, and there is a greater chance of rain. Rapid pressure rises are associated with improving weather conditions, such as clearing skies. Along with pressure tendency, the condition of the sky is one of the more important parameters used to forecast weather in mountainous areas. Thickening of cloud cover or the invasion of a higher cloud deck is indicative of rain in the near future. High thin cirrostratus clouds can create halos around the sun or
