Currently en Puerto Rico — 27 de junio, 2023: Calor excesivo con aguaceros dispersos y tronadas aisladas

El tiempo, currently.

El peligro de calor excesivo seguirá siendo probable cada tarde hasta al menos el miércoles. Las temperaturas alcanzarán el rango bajo de los 90 grados en elevaciones bajas y áreas urbanas, lo que combinado con un aumento en la humedad el martes y el miércoles generará índices de calor de más de 102 grados en la mayor parte del oeste y norte de Puerto Rico. Áreas entre Arecibo y Dorado podrán experimentar índices de calor superiores a los 112 grados. El aumento mencionado en la humedad también impulsará la actividad de lluvia, y tronadas aisladas podrán generar lluvias excesivas en áreas localizadas tanto el martes como el miércoles.

El Niño, the periodic warming of the tropical Pacific Ocean, is back — and it’s getting worse fast.

New data out Monday shows that El Niño has now officially moved into “moderate” territory — with tropical Pacific water temperatures already up to 1.0°C higher than normal. That’s expected to keep growing quickly over the next few months, with a worst-case estimate from Australia’s Bureau of Meteorology showing a peak warming of 3.2°C by November — which would be the strongest El Niño ever measured, by far. Even an average of global predictions now show a peak warming of 2.2°C — meaning that only the El Niños that began in 1982, 1997, and 2015 would be stronger.

The implications of an El Niño this strong are difficult to underestimate. In 2015-16, more than 60 million people worldwide experienced hunger due to drought made worse by the El Niño. The Great Barrier Reef in Australia suffered its worst coral bleaching event in history, with about 30% of the reef losing most of its corals. Pacific Islanders faced a string of the strongest tropical cyclones ever recorded.

Initial research shows that this year’s El Niño could cost the struggling global economy nearly $3 trillion.
