The Kenya Meteorological Department has warned of the coastal region of a weakening low-pressure system, which could bring heavy rains and strong winds from tomorrow.
Met has issued a statement on the low-pressure system Cyclone “Chenge” (Residual Depression) currently over the southwest Indian Ocean.
Chenge, located about 500 km north of Madagascar, continues to weaken as it moves west across the northern Mozambique Channel.
Chenge, which started as a low-pressure area over the southwest Indian Ocean and has winds blowing at around 55 kilometres per hour and gusts reaching up to 75 kilometres per hour as it heads to the East African Coast.
Despite its weakening, the system’s proximity to the coast may influence local weather conditions over southern coastal Kenya and Tanzania early in the week, according to the latest weather alert of Sunday.
“Heavy rainfall is expected over several parts of the country, with strong winds exceeding 25 knots possible along the south coast on Monday and Tuesday as the system dissipates,” Met said in a statement.
Consequently, Met has cautioned residents, particularly in coastal regions and those engaged in marine activities, to exercise caution, stay informed through official KMD updates, and take necessary preparedness measures.
Fishermen and marine operators along the Indian Ocean have been particularly advised to exercise caution due to possible rough seas and strong gusts.
The weatherman has also indicated that Mayotte will not be under cyclone alert, but could experience swells of around two metres between Sunday and Monday.
In an earlier advisory No. 03/2025, issued at 11 am on Wednesday last week, KMD indicated that rainfall currently affecting parts of the Lake Victoria Basin, Rift Valley, and Highlands West of the Rift Valley is expected to intensify to over 30mm within 24 hours, spreading to the Highlands East of the Rift Valley (including Nairobi) and the Southeastern Lowlands from Thursday afternoon.
“The heavy rainfall is expected to continue and extend to parts of the North-Eastern region from Thursday, 30th October 2025. This is likely to mark the onset of the short rains season (OND) over several parts of the country, except parts of the South-Eastern Lowlands and the Coast,” the advisory noted.
The affected counties include Kisumu, Homa Bay, Siaya, Migori, Busia, Kisii, Nyamira, Nandi, Kericho, Bomet, Kakamega, Vihiga, Bungoma, Narok and Baringo.
Others are Nakuru, Trans Nzoia, Uasin Gishu, Elgeyo Marakwet, West Pokot, Turkana, Isiolo, Samburu, Marsabit, Mandera, Wajir, Nyandarua, Laikipia and Nyeri.
KMD advised residents in the listed counties to remain vigilant and take precautionary measures against potential flooding and landslides, particularly in low-lying areas and along steep slopes such as the Aberdare ranges, Mount Kenya, and the western highlands.
“People in landslide-prone areas and flood basins should be on high alert,” said Kennedy Thiong’o, who issued the notice on behalf of the Acting Director of the Kenya Meteorological Department
