The National Weather Service has issued an Excessive Heat Watch for areas across Puerto Rico and the U.S. Virgin Islands from 9 a.m. on Saturday to at least 6 p.m.

“Warmer and stable weather conditions will prevail for the upcoming weekend, [and] as a result, an Excessive Heat Watch remains in place for most coastal and urban areas,” according to an update from the NWS on Friday.

The NWS noted that the hot temperatures are a result of an area of high pressure over the islands, along with a southeasterly wind flow. The NWS has warned that the heat can be hazardous and offered the following advice.

“Do not leave young children and pets in unattended vehicles,” the NWS warned. “Car interiors will reach lethal temperatures in a matter of minutes. Take extra precautions when outside, [and] wear lightweight and loose-fitting clothing. Try to limit strenuous activities to early morning or evening,” the NWS continued.

Residents are encouraged to recognize the signs of heat-related illnesses, such as heat stroke and heat exhaustion, which can occur during hyperthermia. Remaining hydrated and cool is essential, as is noted in a previous Source article regarding extreme heat across the USVI.

“This level of heat affects anyone without effective cooling and/or adequate hydration. Impacts are likely in some health systems, heat-sensitive industries and infrastructure,” the NWS explained.

On Friday, the Source contacted the Virgin Islands Territorial Emergency Management Agency to inquire about cooling centers across the islands for individuals who may not have access to air conditioning or those who have been affected by ongoing WAPA power outages. As of Friday afternoon, cooling areas have not been established, and no plans exist to open any centers.
