Arab Weather - The Egyptian capital, Cairo, and several northern regions witnessed sudden and heavy rainfall yesterday, unusual for this time of year, causing traffic disruption in several areas.
According to meteorological indicators and numerical model analysis, this condition is due to the influence of an upper air depression centered over Turkish territory, which has led to a clear disturbance in the upper layers of the atmosphere over northern Egypt. This coincided with the flow of warm, humid air currents in the lower layers of the atmosphere coming from the southeast across the Arabian Peninsula, contributing to the sudden and rapid formation of cumulonimbus clouds.
This type of atmospheric instability is relatively rare during the summer in Cairo, where stable and dry conditions typically prevail. However, this convergence of the cold upper mass and the moist lower currents has created a favorable environment for the emergence of unstable weather conditions.
Such cases are rare and are not expected to occur in any of Egypt's neighbouring countries.
