Currently in Miami — June 27, 2023: Scattered showers and isolated thunderstorms; Aguaceros aislados y tormentas eléctricas aisladas en la tarde

The weather, currently.

Rain chances will be slashed from the 60-70% range on Monday to the 30-40% range on Tuesday as drier air in the mid-levels of the atmosphere intrudes over South Florida. The chances of strong afternoon thunderstorms will also diminish, although not completely. Isolated thunderstorms could still produce strong wind gusts, heavy downpours, and frequent lightning. Despite these changes, temperatures will remain hot with afternoon highs in the low-to-mid-90s and overnight lows in the low 70s. Later in the week, there is potential for record-breaking temperatures and dangerous heat indices in the triple digits. Look out for Heat Advisories later this week.

El tiempo, currently.

Las posibilidades de lluvia se reducirán del rango de 60-70% el lunes al rango de 30-40% el martes a medida que aire más seco en los niveles medios de la atmósfera se entromete sobre el sur de Florida. El potencial de fuertes tormentas eléctricas por la tarde también disminuirá, aunque no del todo. Tormentas aisladas aún podrían producir fuertes ráfagas de viento, diluvios y relámpagos frecuentes. A pesar de estos cambios, las temperaturas permanecerán altas, con temperaturas máximas vespertinas entre los rangos bajo y medio de los 90 grados y mínimas nocturnas en el rango medio de los 70. Más adelante en la semana, existe la posibilidad de temperaturas récord e índices de calor peligrosos en los tres dígitos. Esté atento a las Advertencias de Calor a finales de esta semana.

What you need to know, currently.

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.
