A beach hazards statement is out on area beaches from Monday night into Tuesday evening due to building waves and the risk to swimmers of rip currents.

Heat & Humidity Next

Summer’s hottest readings could be on the way starting next weekend and into next week.

A series of 90-deg and hotter days is likely with dew points surging—means the heat will be accompanied by high humidities thus likely producing triple digit heat indices from Sunday forward through next Tuesday.

The hotter and drier weather is expected to last through next Tuesday.

To date, the city’s hottest temps have hit 93 degrees this summer. Absent cooling thunderstorms, this air mass could produce mid to upper 90s—particularly in the Sunday through Tuesday time frame this weekend and next week.
