DHAKA: The US National Weather Service (NWS) has admitted its forecasts were wrong, after predicting a ‘potentially historic blizzard’ would strike.

The storm piled deep snow on Connecticut and Massachusetts, but New York City was largely spared.

The city's mayor, Bill de Blasio, defended claims he had overreacted to warnings, saying he had only acted on the information available.

Blizzard warnings remain along the coast from Long Island to Maine.

‘Rapidly deepening winter storms are very challenging to predict,’ the NWS wrote on its Facebook page.

The storm has moved further east and will be departing faster than our forecasts of the past two days, reports the BBC.
