Across Southern Florida:
Life-threatening flooding caused by excessive heavy rainfall from strong thunderstorms continuously training over the same region persists in the southern portions of Florida. Additional significant rainfall is anticipated, which will further exacerbate the situation. Refer to the detailed forecast for further specifics below.
Overall Forecast:
Life-threatening flooding is ongoing as heavy rain and thunderstorms, some of which may be strong to severe, continue across Florida, particularly in the southern regions, through at least the end of this week. A stalled frontal boundary across northern Florida is providing lift and enhancing moisture influx across the region. In the mid/upper levels, a shortwave over the Deep South extends into the northern Gulf, while high pressure over the central Atlantic is pushing significant moisture into Florida. This is particularly evident in the southern part of the state, where precipitable water (PW) values are at record levels, leading to significant heavy rainfall.
In the coming days, a subtropical jet stream will remain over Florida, positioned above a positively tilted significant shortwave trough. This setup will continue to feed deep moisture into the area, resulting in more significant heavy rainfall and widespread flooding, especially along the southern coasts.
Significant heavy rainfall has already accumulated across southern Florida, with more excessive rain expected. An additional 3-5 inches of rainfall is anticipated, with local amounts reaching as high as 10 inches in some areas, such as the southwestern portions of the coast. This will likely lead to widespread flooding.
Main impact: heavy rain leading to flooding, CG lightning (cloud to ground), small hail, local gusty winds, brief tornado and waterspouts.
