Brooklyn is experiencing what could be its fourth heat wave of the summer. With a heat advisory in place, the city is expected to activate its new lifeguard policy.

Earlier this week, Mayor Eric Adams announced lifeguards will extend their hours on the city's beaches until 8 p.m. when the city's heat emergency plan is activated. However, this extension does not permit swimming beyond the usual 6 p.m. cutoff.

City officials say a skeleton crew of around 66 lifeguards will be stationed at their shacks rather than their chairs. They'll be able to respond in case of an emergency.

The new policy comes barely one month after two teenage girls drowned in Coney Island after swimming when the water was off limits.

During this heat advisory, residents are advised to stay hydrated, avoid direct sun exposure during peak hours, and seek shade to mitigate the effects of the heat.

For those without access to air conditioning, the city's cooling centers are open.

The heat advisory is in effect through tomorrow evening, with temperatures expected to remain high.
