Official reports have said a tropical storm Cyclone Chalane is expected to hit Manicaland parts of Madagascar and parts of Mozambique this week till next week, AccuWeather reports.
According to AccuWeather Senior Meteorologist Jason Nicholls, the storm will strengthen as it drifts from its point of origin in the Indian Ocean.
A tropical low located well southwest of Diego Garcia will continue to strengthen as it drifts westward over the next few days.
As this tropical depression slowly drifts westward, it will enter an area of atmospheric conditions that will likely allow for further strengthening.
To strengthen, tropical systems need at least two main atmospheric ingredients warm waters and a lack of vertical wind shear.
Vertical wind shear, which is the change in direction and speed of winds at increasing heights in the atmosphere, is forecast to remain low across the southwestern Indian Ocean throughout the week.
Warm water and favorable atmospheric conditions are expected to allow this low to strengthen into Tropical Storm Chalane this week.
As the storm strengthens, it will continue to track slowly westward into the weekend.
The tropical depression likely to be named Chalane can strengthen enough to achieve moderate or severe tropical-storm status, as designated by Météo France’s La Réunion, later this week
Nicholls further explained the areas that will be hit by the expected storm:
As the storm approaches northern Madagascar late this week, periods of tropical rainfall, gusty winds and rough seas will begin to increase across the region.
The storm is expected to strike northeast Madagascar on Saturday and may eventually emerge over the Mozambique Channel and Zimbabwe early next week, local time
According to the publication, the heaviest rainfall of Cyclone Chalane (between 100-200mm) will mostly impact northern Madagascar and the country’s eastern coast from late Friday through Monday and it will likely lead to flooding and mudslides.
Last Year Zimbabwe and Mozambique were hit by another storm Cyclone Idai which left thousands dead and thousands more homeless.
