Currently in Miami — September 12, 2023: Stronger onshore breeze will push rains west

The weather, currently.

A shift to northeasterly winds on Tuesday will focus the majority of the day’s rain activity over the Everglades, so the east coast metro area will likely remain dry. And while temperatures will remain in the low to mid 90s, humidity will not be too high, so heat indices will stay just above 100 degrees. Later in the week, high pressure will develop in the mid to upper levels of the atmosphere that will promote stability and limit rain chances. Expect scattered showers and the occasional isolated thunderstorm during the early afternoons. Marine conditions will be prime for boating, with seas generally between 1 to 3 feet early this week, as swells from distant Hurricane Lee are not yet a factor.

El tiempo, actualmente.

Un cambio a vientos del noreste el martes concentrará la mayor parte de la actividad de lluvia del día sobre los Everglades, por lo que el área metropolitana de la costa este probablemente permanecerá seca. Y aunque las temperaturas se mantendrán en los rangos bajo a medio de los 90, la humedad no será demasiado alta, así que los índices de calor se mantendrán justo por encima de los 100 grados. Más adelante en la semana, se desarrollará alta presión en los niveles medios y superiores de la atmósfera que promoverá estabilidad y limitará las posibilidades de lluvia. Espere aguaceros dispersos y tormentas eléctricas aisladas durante las primeras horas de la tarde. Las condiciones marinas serán favorables, con mares generalmente entre 1 y 3 pies a principios de esta semana, ya que las marejadas del distante huracán Lee no son un factor todavía.

What you need to know, currently.

The Kīlauea volcano on the big island of Hawai’i began erupting on Sunday afternoon — its fifth eruption in the past four years.

Kīlauea is one of the most active volcanoes on Earth, so this really isn’t a surprise, but it’s still a literally awesome reminder that we all live on a planet that is continually in motion at all space and time scales.

The Hawaiian islands were formed over the past 50 million years by the same plume of upwelling undersea magma in the middle of the Pacific. The island of Hawai’i is the largest and youngest island of the chain — Kīlauea emerged from under the ocean just 100,000 years ago. In 2018, the volcano’s summit collapsed and released a lava flow up to 500m (1600ft) thick that destroyed hundreds of homes and marked a shift into its current eruptive phase. In contrast, this week’s eruption is extremely minor — but still impressive.

The US Geological Survey has set up a live view of the eruption in Kīlauea’s Halemaʻumaʻu crater:
