Currently in Miami — September 29, 2023: No change to the wet weather
Plus, a flash flood threat for NYC.

The weather, currently.
Still wet
The stalled frontal boundary over northern Florida, which has acted as a wall for incoming moisture from the southeast and allowed it to pool over South Florida all week, refuses to budge, meaning that more rainy days are expected on Friday and over the weekend. Showers will be numerous on Friday with several thunderstorms likely that will generate heavy downpours in some areas, especially to the north of Alligator Alley. With soils and drainage systems already saturated from previous rain this week, flood risk will be high, particularly in urban areas. Much of the same is expected on Saturday, but a shift to northeasterly winds at the turn of the new week will lead to the influx of drier air, and thus drier weather.
El tiempo, actualmente.
El frente estancado sobre el norte de Florida, que ha actuado como un muro para la humedad entrante desde el sureste y le ha permitido acumularse sobre el sur de Florida durante la semana entera, se niega a moverse. Eso significa que se esperan más días lluviosos el viernes y durante el fin de semana. Los aguaceros serán numerosos el viernes y es probable que varias tormentas eléctricas generen fuertes aguaceros en algunas áreas, especialmente al norte de Alligator Alley. Dado que los suelos y los sistemas de drenaje ya están saturados por las lluvias anteriores de esta semana, el riesgo de inundaciones será alto, especialmente en las zonas urbanas. Se espera lo mismo el sábado, pero un cambio a vientos del noreste al comienzo de la nueva semana traerá aire más seco y, por tanto, tiempo más seco al sur de Florida.
What you need to know, currently.
An extremely heavy rainstorm is forecast for Friday near New York City, with the potential for record-setting rainfall that could create widespread flash flooding.
Heavy rain — 4-6 inches — is expected over a wide swath of metro New Jersey, NYC, the Hudson Valley, and western Connecticut. In an extreme situation — if everything lines up perfectly — some locations in Brookyn, Queens, or Nassau county could get upwards of 6-12” of rain or more. In a worst case scenario, the state’s all-time 24-hour rainfall record could be in jeopardy. (13.57” at Islip on Long Island set on Aug 14, 2014).
[Key Messages]: Heavy rainfall likely with potential of scattered to numerous areas of flash flooding late tonight into Fri night. Flood Watch is in effect for much of the area during this time. Closely monitor the forecast & prepare to take action if warnings are issued.

Water temperatures in the Atlantic Ocean just off the East Coast have been at record levels all summer, the perfect fuel for excessive rain. And a slow-moving storm system is all it will take for this fuel to turn into a major flood threat.
