Currently in Miami — August 8, 2023: Oppresive heat is back

The weather, currently.

Oppressive heat will be the main story in South Florida again into midweek, despite drier air working its way into the region. Temperatures will rise into the mid to upper 90s on Tuesday, and there will be enough humidity to drive the heat index to 105-112 degrees. Heat Advisories are likely, indicating the importance of staying hydrated and avoiding outdoor activities when possible. Showers and thunderstorms will still be possible on Tuesday, but the influx of drier air will keep the threat of strong to severe storms at bay, while also focusing the majority of the rain activity inland and away from the east coast metro area.

El tiempo, actualmente.

El calor opresivo seguirá siendo el tema de conversación hasta al menos mediados de semana a pesar de que está llegando aire más seco a la región. Las temperaturas calentarán a los rangos medio y alto de los 90 grados el martes, y habrá suficiente humedad para llevar los índices de calor a 105-112 grados. Es probable que se emitan Advertencias de Calor, lo que enfatiza la importancia de mantenerse hidratado y evitar las actividades al aire libre cuando sea posible. Los aguaceros y tormentas eléctricas seguirán siendo posibles el martes, pero el ingreso de aire más seco mantendrá a raya la amenaza de tormentas fuertes o severas, mientras que también concentrará la mayor parte de la actividad de lluvia tierra adentro y lejos del área metropolitana de la costa este..

What you need to know, currently.

After curving eastward at the last minute, Typhoon Khanun is now bearing down on the Korean Peninsula.

Parts of eastern North Korea could receive up to 500 mm (20 in) of rain in just 48 hours later this week as Khanun passes through. It’s the latest weather disaster in North Korea after a drought-filled spring prompted a food crisis, and heat waves and heavy rains plagued the authoritarian state in July.

There have been only 5 typhoon-strength storms to make landfall in North Korea since complete records begin in 1945. Khanun is expected to restrengthen over the next two days and traverse directly over Seoul, South Korea, while directing most of its strongest wind, storm surge, and rainfall on the eastern half of the Koreas.

Khanun will only be able to restrengthen because it will be traversing some of the most unusually warm water in the world between Japan and the Koreas, approximately 4-5°C (7-9°F) hotter than normal. That will also act to enhance the rainfall it produces.

Last week, Typhoon Doksuri brought Beijing its largest rainstorm in recorded history, and had Khanun taken a similar track, it would have greatly compounded flooding in China.
