CITY OF NEWBURGH — City officials in Newburgh will open some fire hydrants on Overlook Place and South Lander Street to help children and families find relief from the heat this weekend.

To temper the flow, the city's Water Department will place sprinkler caps on the hydrants that will make it easier for children to run around and catch a cool spray.

Weather forecasters are predicting high temperatures in the mid-90s on Saturday and Sunday, with heat indexes expected to be between 100 and 110 degrees throughout the Hudson Valley.

The National Weather Service has issued excessive heat warnings for Orange, Ulster and Sullivan counties until 8 p.m. Sunday. The agency warns people who spend prolonged periods in the heat over the weekend could experience dangerous heat-related illness.

Newburgh officials said the city's concrete, metal and asphalt infrastructure can create a heat trap and can cause temperatures there to hover around 10 degrees hotter than surrounding areas, which is often referred as an urban heat island effect.

Several local governments are opening municipal buildings as cooling stations and some are extending public pool hours, like the City of Newburgh.

The Aquatic Center at Delano-Hitch Park in Newburgh will be open to the public from 12:30-8 p.m. Saturday.

Newburgh's playground-on-wheels will set up at the corner of Overlook Place and South Lander Street, as well as the city's Recreation Department, between 11 a.m.-5 p.m. Saturday. The Recreation Department is located behind the Activity Center at 401 Washington St.
