SAN DIEGO - A main break has left hotels, restaurants and other businesses on Harbor Island without water on Monday.

According to the San Diego Water Department, crews are working to repair the break and that the water supply should be back on at noon or 1 p.m.

A contractor hit a water main that supplies Harbor Island at around 11 p.m. Sunday night, according to a spokesperson with the water department. The main is located at the intersection of Harbor Island Drive and North Harbor Drive. The rupture shut off water for all restaurants and hotels in Harbor Island.

The break occurred as San Diego is expecting high temperatures throughout Monday and Tuesday. Inland valley areas are expected to hit mid 90s to 100.  Coastal communities will be cooler but will still feel the heat, with temperatures in the 80s and 90s.

A manager with Hilton Hotel and Resorts said the 211-room hotel is impacted because all of its rooms are currently sold out. Likewise, the manager said, the Sheraton Marina has booked all of its 1,100 rooms. In addition the Sheraton is expecting about 2,000 attendees to a meeting event.
