Naval Air Station Sigonella officials are offering emergency housing to U.S. military and civilian personnel and their families living off base who are facing blackouts.

The extreme heat, reaching as high as 118 degrees, is putting pressure on the island’s power grid and basic services. Outages have curbed the use of air conditioners and fans and in some cases hurt the ability of cities, such as Catania, to supply drinking water, the Italian news agency Ansa reported Monday.

So far, two families have moved into base housing and four more have found other arrangements, said Lt. j.g. Andrea Perez, a spokeswoman for the base, which is about 12 miles south of Catania.

More than 1,900 active-duty and civilian personnel and dependents live in communities near the base, she said.

Capt. Aaron Shoemaker, the base’s commanding officer, encouraged families experiencing blackouts and limited access to air conditioning to call the base’s housing department for assistance.

On Tuesday afternoon, it was 108 degrees in Catania, according to BBC Weather. The average daily high has been 100 degrees or greater over the past week, but a cooldown is expected Wednesday, according to the BBC.

Cities across Italy have been dealing with blackouts because of increased power consumption in the scorching heat.

The city that hosts Naval Support Activity Naples and NATO Joint Force Command Naples registered a temperature of 91 degrees with 63% humidity Tuesday afternoon, making it feel like 104 degrees, according to weather.com.
