US central bankers are sharply divided over whether to increase interest rates again this year amid persistently weak inflation, but many still favor a hike, meeting minutes released Wednesday showed.

Policymakers also said the economic effects of hurricanes Harvey, Irma and Maria, which tore a path of destruction across US territories between August and September, were likely to be only temporary, according to a record of the Fed's most recent meeting last month.
