JOHANNESBURG, March 14 (Reuters) - A powerful hurricane threatening to rip through Mozambique's second largest port with winds of over 190 kilometres per hour is expected to make landfall late on Thursday, South Africa's Weather Service said.
Cyclone Idai is set to hit Mozambique and Malawi with strong winds and heavy rain, high seas and storm surges, dumping more water and destruction on areas where scores have already been killed and tens of thousands displaced by floods over the past week.
In a tweet, the weather service said the storm is expected to hit land on Thursday evening within 60 kilometres of Beira, the country's fourth largest city, bringing "life-threatening" storm surges of 3-4 metres, rising to 5-6 metres in a river running from the port city to Zimbabwe.
Images on Twitter already showed some bad weather at Beira, a gateway for imports to landlocked countries in south-east Africa, with billboards and telephone poles pulled down by winds.
The storm threatens a familiar natural disaster in Mozambique, which has already seen deadly floods worsened by devastating hurricanes in both 2000 and 2007.
Cyclone Eline, which hit the country in February 2000 when it was already devastated by its worst floods in three decades, left 350 dead and 650,000 homeless across southern Africa. Whole cities were left without access to clean water, sanitation or electricity.
Citing government officials and media reports, the United Nations said more than 100 people had already died in heavy rains and flooding in Mozambique and Malawi, where villages were left underwater and floods washed away houses and knocked out power in some areas.
Almost 100,000 people had been displaced across the two countries, it said, with humanitarian operations already underway in both and a red alert issued in Mozambique ahead of the storm.
Cyclone Idai also follows Cyclone Favio, which battered southern Mozambique with winds of up to 230 kilometres, uprooting trees, knocking over electricity pylons and worsening deadly floods.
Mozambique has significant offshore liquefied natural gas projects underway in the north, but these were currently out of harms way.
"At this time, given its projected path, Cyclone Idai is not anticipated to impact activity at the site," a spokesman for U.S. energy company Anadarko, which has a project in the region after a huge gas discovery, said.
An Exxon Mobil spokeswoman also said it didn't have any operations in affected areas. (Reporting by Emma Rumney; Additional reporting by Alexander Winning; Editing by Toby Chopra)
