As from Sunday 23 February to Sunday 1st March, 2020 there will be a wave of widespread thunderstorms passing through the country starting from the south and eventually moving to the centre and eventually northern areas caused by the Inter Tropical Convergence Zone as it crosses the country, leaving the south with meager and reduced rainfall activities. This will result in most areas in the south to experience erratic and isolated thunderstorms interspaced with dry weather conditions particularly over the extreme south, while thunderstorm rainfall activities inter-spaced with heaviest episodes will be over the north and central areas of the country during most days of the week.
Locally heavy downpours which could result in swelling of rivers due siltation is likely to trigger floods particularly over northern lakeshore areas. The general public is advised to avoid crossing swelling rivers.
To avoid being struck by lightning whenever thunderstorms occur in the vicinity, the public is advised to be in doors, stay away from windows and doors, not swim or fish, stay at a low spot away from trees, metal fences, pipes, tall or long objects and not sit on verandahs
The sunlight intervals are necessary for the due process of photosynthesis in green plants to take place when the plants use the energy from the sun light to convert water, carbon dioxide and minerals into oxygen and organic compounds packed with energy as the light energy gets absorbed by chlorophyll in the green plants.
The general public is encouraged to take advantage of any rains to carry out rainwater harvesting including drilling of boreholes to be used for irrigation during any mid-season dry spell. To enhance reduction of future catastrophic floods, storage of soil moisture and to act as wind breaks during strong winds, tree planting activities should continue.
City, town, road authorities and community leaders should relentlessly continue ensuring that storm-water drainage systems are well managed, clear of rubbish and filling up potholes on the roads to ease flow of storm-water runoff.
Meanwhile the Department of Climate Change and Meteorological Services is closely monitoring weather developments over the country including in the South West Indian Ocean and in the Mozambique Channel where tropical cyclone formation can occur.
The public is relentlessly being strongly advised to religiously pay undivided attention to the continuously available daily, 10-day and weekly weather updates from the Department of Climate Change and Meteorological Services to ensure seamless use of weather information on all timescales and therefore be kept safe from any weather related threats.
