Rwanda Meteo Agency has forecast that from April 21 to 30, the amount of rainfall is expected to increase.
Enhanced cumulative rainfall ranging between 130 and 150 mm is the highest and is expected over Rubavu and Rutsiro districts, many parts of Nyamasheke, Nyabihu, Burera, Musanze, Gakenke and Rulindo districts and western parts of Gicumbi, Karongi and Ngororero districts.

Cumulative rainfall ranging between 50 and 70 mm is the lowest amount expected during the forecasting period and is expected over eastern parts of Nyagatare and Kirehe districts.
"Impacts associated with heavy rain, thunderstorms and wind such as flooding on road surfaces, localized agricultural areas, flood-prone areas, slippery roads and poor visibility during rainstorms may lead to poor movement of vehicles, landslides in areas of high slopes, blowing off of roof tops, falling of leaves and small branches, and damages caused by lightning and thunders are likely to occur and mitigation measures should be put in place,” the weatherman has warned.
"The predicted rainfall will also be associated with wind storms weather patterns.
Strong winds ranging between 6 and 9 metres per second is expected over Nyagatare, Kirehe, most parts of Gatsibo, Nyanza, Karongi, Nyamagabe, Rusizi, Gicumbi and few parts of Rulindo, Kamonyi, Muhanga, Ngororero, Rutsiro, Nyabihu, Gakenke and Rubavu districts.
Moderate wind ranging between 4 and 6 m/s is expected over the remaining parts of the country.
Safety tips
The City of Kigali, on Sunday, also urged people in high risk zones to relocate.
"Rainwater drains should also be unclogged across the city, harvest rainwater and relocate from houses that have signs of collapsing. Slopes close to houses should be protected to avoid collapse,” it tweeted.
"People should avoid driving and people must be inside the houses and not under trees during heavy rain. People should also avoid standing in water and should avoid using mobile phones while it is raining, they should also unplug electric equipment,” reads part of the tweet.
The safety tips also advise strengthening roofs and ceilings and planting trees around houses to curb strong winds.
"While constructing, the doors and windows should not face wind direction. In areas that usually face strong winds, long walls that protect roofs and ceilings must be built,” say the guidelines.
The City of Kigali is also conducting studies on six high critical flooding spots and a storm water management master plan mitigate floods in the long-term.
The six flooding spots in Kigali include Rugunga, Gisozi-Umukindo, Rwandex, Kinyinya and Nyabisindu among others.
According to MINEMA, farmers are advised to apply anti-erosion measures by constructing terraces, anti-erosion ditches and planting trees to avoid soil degradation and retain run-off water.
