A “noticeable rise in temperature” is expected in different parts of the country from Friday until Sunday, the Qatar Met department has said.
Strong winds are expected in some places in the early hours of Monday. Windy conditions and high seas are also likely in offshore areas.
The Met department said scattered light rain had been detected in the northern areas along with partly cloudy skies.
The wind speed (northwesterly) may go up to 25 knots in some places inshore and 35 knots offshore, with the sea level rising to 12ft. Visibility, meanwhile, may drop to 2km or less at times.
