BASED on averages of previous seasons, five cyclones are expected to reach Zimbabwe in the current rainy season, although there are no predictions of when, where they could strike, and their strengths.
But the Government has drawn valuable lessons from past cyclones and put in place measures to warn and protect people even should a high-energy cyclone with extreme rainfall hit.
Speaking during the National Tobacco Workshop, an agriculture meteorologist at the Meteorological Services Department, Benjamin Kwenda, said there would be an increase in cyclone activity from next month, with the risks being high over the next four months during the cyclone season.
“This season we are anticipating an increase in cyclone activity in January, February, March up to April but in terms of projections we are expecting five cyclones,” he said.
It was only when a cyclone finally formed in the Indian Ocean that it would be possible for meteorologists to start working out their likely path and updating that information frequently as the cyclone started moving towards Madagascar and Africa.
But even so the warnings were fairly short-term as the storms were unpredictable.
“The tropical cyclone, its just like a whirlwind so when the whirlwind is generated you are not able to pick where exactly it will go but as it grows bigger you will then able to pick the direction and then you can actually say this is where it is going,” said Mr Kwenda.
He said the Met Department was expecting rains into next week. There would be a decline of rainfall up to Wednesday next week, with some places experiencing sunny conditions.
The first half of the season, up to the end of the year, the expectation was that most of the country would be in the category of normal to below-normal, but the southern parts would see normal to above-normal totals.
“For the period December, January and February we are expecting the bulk of the country to receive normal to above-normal rainfall in this season and this is the same that we are expecting in January, February and March. We are generally looking for a better season in terms of seasonal totals,” he said.
The Met Department saw a possibility of having more frequent extremes, such as hailstorms, and so there was a need for crop insurance because that was the only way farmers could cope with losses to their crops.
Hail is ideally suited to insurance, since the odds of destruction of a crop on any particular farm is low, so premiums can be low, but if a hailstorm does move over a farm, the damage is extreme, and the insurance payout is vital.
The Government has been budgeting to ensure that adequate responses can be made for storm and flood damage.
Recently, the Department of Civil Protection chief director Mr Nathan Nkomo said adequate funds to deal with disasters such as flash floods associated with the rainy season have been set aside.
“The rainfall season comes with a lot of challenges, but more importantly, it also comes with a lot of hope because most of our agriculture is rain-fed. So we welcome the rainfall season in Zimbabwe. However, in terms of preparedness, we have done our level best. Remember we are preparing to handle natural hazards in the form of flash floods and ultimately, when we get into the cyclone season, mostly from January to March, we will escalate our level of preparedness,” he said.
Zimbabwe Farmers’ Union economist Ms Nyasha Taderera said staggering of crops is critical when the floods occur because not all crops will be affected. Diversification was crucial tp spread risk, hence a need to plant different types of crops.
“Cyclones are usually accompanied by dry spells so not all crops will be destroyed. The effects of floods are different to crops. Some can be totally destroyed but some may survive,” she said.
Zimbabwe Commercial Farmers’ Union president Dr Shadreck Makombe urged farmers to stay away from river banks adding that farmers should take all warnings seriously to keep themselves safe.
“Safety is of paramount importance. Do not ignore these key messages. Growing of crops on vleis may also trigger leaching so I advise farmers to note this crucial information so that they are protected from dangerous effects of weather,” he said.
Tropical Cyclone Idai, the worst in more than 50 years to reach Zimbabwe, brought heavy rainfall and strong winds to Malawi, Mozambique and Zimbabwe between March 5 and 19 in 2019, causing severe flooding which led to loss of lives, destruction of infrastructure, disruption of livelihoods and destruction of crops.
It is estimated that close to 780 000ha of crops in the three countries were destroyed or damaged by the cyclone, with most of this damage being in Mozambique. Dams and wells were also damaged, and livestock was washed away. SADC launched a US$323 million appeal to support the disaster response and recovery efforts related to the impact of Tropical Cyclone Idai.
