Sept 29 (Reuters) - Lloyd's of London insurer Beazley Plc estimated losses from Atlantic hurricanes Harvey, Irma and Maria and a series of earthquakes in Mexico would reduce its 2017 earnings by about $150 million.
The insurer's early estimates point to aggregate net cost from the hurricanes and earthquakes of between $175-$275 million, it said on Friday.
Beazley said it would provide a further update on Nov. 9, adding there is still significant uncertainty surrounding the cost of these events.
Insurers and reinsurers are counting the costs of Harvey, which lashed Texas causing flooding that put it on the scale of Hurricane Sandy in 2012 and Irma, one of the most powerful Atlantic Ocean storms on record, which ravaged several islands in the northern Caribbean, before barrelling into Florida's Gulf Coast.
Most recently, Maria, the most powerful hurricane to hit the U.S. island territory of Puerto Rico in nearly 90 years, knocked out the territory's entire power grid, unleashing severe flooding and causing widespread heavy damage.
Lloyd's of London said on Thursday that it expects net losses of $4.5 billion from hurricanes Harvey and Irma, which analysts said would eat into the insurer's capital and hit its profitability.
Modelling firm RMS estimates total insured losses from Harvey and Irma of up to $80 billion and $15-30 billion of losses from Hurricane Maria.
Additionally, rival modelling firm AIR Worldwide earlier this week estimated insured losses for Maria of $40-$85 billion.
Beazley's warning follows a host of similar announcements from insurers and reinsurers.
Underwriter Hiscox estimated it would face net claims of about $150 million from Hurricane Harvey and said it has yet to determine losses from Hurricane Irma.
German reinsurer Hannover Re said it could miss its 2017 profit target, its first such warning since the 2008 financial crisis, following rival Munich Re which was the first major reinsurer to flag a hit to earnings from hurricanes Harvey and Irma.
U.S. property and casualty insurer Chubb Ltd on estimated after-tax losses of up to $1.28 billion from hurricanes Harvey and Irma and Allstate Corp estimated pre-tax catastrophe losses of $593 million, net of reinsurance recoveries, for August.
