As from Sunday 22 March to Sunday 29 March 2020, most of the areas in the south of the country are likely to experience cool to warm and dry weather conditions with sunny intervals with occasional rain showers, particularly over highlands. However, most of the areas in the centre and north are likely to experience cloudy weather conditions with few but locally heavy thunderstorms with occasional sunny intervals due to the interaction of cool and moist airflow from the south east with airflow from the east, enhanced by heating during sunny intervals, and lifting of airflow over high ground.
The general public is encouraged to take advantage of any rains to carry out rainwater harvesting, a process of collection and storage of rainwater from surfaces on which rain falls into natural reservoirs or tanks such as rooftop rainwater harvesting including drilling of boreholes to be used for irrigation.
At night and morning hours motorists should excise caution due to reduced visibility caused by the occurrence of fog in prone areas caused by drop in temperatures during any rainfall episode.
The public is also encouraged to continue carrying out tree planting and management activities to enhance reduction of future hazards such as floods and strong winds whose severity and frequency continue to increase due to climate change, rapid urbanization, and population growth.
City, town, road authorities and community leaders should continue ensuring that storm-water drainage systems are clear of rubbish to ease flow of any storm-water runoff.
During the past week from 15 to 22 March 2020 highest daily rainfall figure of 117.4 millimeters was reported at Iponga weather station.
In terms of volume, rainfall amount of 1 mm supplies 1 litre of water to each square metre of the field. Therefore at Iponga weather station which received 117.4mm on 16 March 2020 means every square metre of the field at Iponga received 117.4 litres of rain water on that day.
The general public should always pay due attention to daily and weekly weather forecast updates from the Department of Climate Change and Meteorological Services to ensure seamless use of weather information on all timescales by the public and to be kept safe from any weather related threats.
