Tropical Cyclone Ialy raises concern as Weatherman predicts heavy rainfall

Kenya Meteorological Department forecasts heavy rainfall through to Wednesday


Tropical Cyclone Ialy which formed in the Indian Ocean south of Seychelles on Tuesday last week moving at 35 kilometres per hour has gained strength and is currently a severe Tropical Cyclone moving at 100 kilometres per hour.

According to the tracking system and Climate Scientists, Tropical Cyclone Ialy is expected to reduce in intensity beginning Monday morning to a moderate Tropical Storm at 95 kilometres per hour.

What is different between Tropical Cyclone Ialy and its sister Hidaya is that its path is northwards towards the equator and will move to close to 3 degrees South before dissipating at a low speed of 55 kilometres per hour.

The eye of the storm will not make landfall and will end in the sea. The cyclone is accompanied by strong winds hence the need for those engaged in fishing to be cautious.
