An extension of low pressure from east, with an upper air low pressure, associated with medium and high clouds with easterly winds will cause suspended dust during next coming days.

Humidity is expected to rise during the night and early the next day, with the probability of mist formation in the north of the UAE. Conditions will be slight to moderate in the Arabian Gulf.
