For the first time, meteorologists issued a heat advisory covering all of Puerto Rico, grappling with persistent power outages under severe heat conditions.
The advisory, which also includes the US Virgin Islands, marks a significant escalation as all 78 municipalities of the US territory now face heightened heat alerts.
Unprecedented heat alerts extend beyond coastal regions
Historically, Puerto Rico’s heat advisories were confined to coastal areas, but the recent conditions have led to a broader warning that encompasses the entire island.
This expansion is a first since the inception of the heat alert system six years ago.
Coastal regions are particularly hard-hit, with heat indexes predicted to soar up to 114 degrees Fahrenheit (about 46 degrees Celsius) through Wednesday morning, exacerbated by a dense cloud of Saharan dust.

Saharan Dust intensifies heatwave conditions
A substantial influx of mineral dust from West Africa, known as Saharan dust, has blanketed Puerto Rico, contributing to the oppressive heat levels.
This phenomenon not only worsens the heat experience but also poses significant health risks, particularly to individuals with allergies or compromised immune systems.
The advisory period, set from 10 a.m. to 6 p.m., aims to mitigate exposure during the most intense heat hours.

Climate change and rising temperatures
The widespread heat advisory underscores the growing impact of climate change, with rising ocean temperatures contributing to more severe heat episodes across the island.
The proactive dissemination of these advisories is intended to enable residents and visitors to make informed decisions regarding their health and safety during these extreme weather conditions.
