The episode as NWS MFL wrote it up.
A plume of deep tropical moisture streamed into South Florida during the week of June 10 through 15th as the region remained south of a stationary boundary and in close proximity to a weak tropical disturbance. Multiple mesoscale convective systems developed to the south of this boundary over Central Florida and gradually pivoted southward into South Florida during the morning and afternoon hours of June 11th, 12th, and 13th, 2024. With a very moist and warm atmospheric composition, rainfall rates were efficient and tropical in nature. Storm total rainfall of up to 20 inches occurred across NE Miami-Dade and SE Broward counties, with totals as high as 18 inches in the Big Cypress National Preserve in Collier County. These rainfall totals resulted in major flooding across these areas.

Area Forecast Discussion
National Weather Service Miami FL
706 AM EDT Tue Jun 11 2024
...New AVIATION...
.SHORT TERM...
(Today through Wednesday)
Issued at 152 AM EDT Tue Jun 11 2024
A cold front and associated weak surface low is currently
progressing into northern Florida this morning, with the front
projected to stall in that general area through the short-term
period. At the mid-lvls, longwave troughing will be in place over
the eastern CONUS with ridging pinned to our southeast (centered to
the SW of the Turks and Caicos). This configuration will result in
strengthening deep-layer SWrly flow overspreading our area, which
will in turn transport rich tropical moisture, characterized by
PWATs around 2.5 inches (approx 3 SD above climo) NEwrd into SFL
today. This anomalous moisture plume, which will largely remain
pooled over South and Central Florida over the next several days,
will set the stage for an active and wet pattern over our area.
In terms of forecast details, the overnight CAMs continue to
highlight the threat of heavy rainfall and locally very heavy
rainfall over portions of our area through Wednesday. In large the
highest totals look to be focused over SWFL where low-lvl
convergence will be maximized in the SWrly regime. However, the
anomalous moisture and deep warm-cloud layer will enable efficient
warm-rain processes, and any convective elements that can form (in
the limited instability tropical environment) will be capable of
high rain rates and localized flooding concerns... with the more
widespread flooding concern being dictated by which areas can
receive repeated rounds from these heavy rainers. Consequently the
flood watch remains in effect for the entire area through Wednesday
night, although as will be discussed in the long term, the hydro
threat will likely linger into the latter half of the workweek.
In terms of specific rainfall amounts, the HREF means yield
widespread totals of 2-4 inches across SEFL through Wednesday
afternoon, with 3-7 inch totals over SWFL. The Probability Matched
Mean (PMM), which is likely more representative of higher-end (but
not necessarily the absolute maximum values) in this regime, would
bump those ranges to 3-6 inches over the east coast and 6-10 inches
over portions of SWFL. Individual CAMS even depict some very
localized maxima of 10+ inches (in just the next 36-48 hours)
largely over SWFL. Our forecast QPF values are a blend of the more
conservative (but likely decent as an area-average) HREF mean, and
the more aggressive PMM values that may better capture the higher
end possibilities. However, it must be emphasized that large spatial
gradients in totals are very likely given that the tracks of
individual poorly-organized convective cells will likely drive
totals, and these tracks are nearly impossible to predict with much
lead-time.
Outside of the periods of heavy rain and associated flooding
concerns, a silver lining will be the somewhat cooler temperatures
as abundant cloud cover and periods of rainfall should keep highs
only in the low to mid 80s through Wednesday.

.LONG TERM...
(Wednesday night through Monday)
Issued at 152 AM EDT Tue Jun 11 2024
The wet and active period will continue for the first half of the
extended period as the boundary to our north remains stalled and the
tropical moisture remains focused over south-Central Florida. A mid-
lvl shortwave trough will pivot southeastward and phase with the
longwave east-coast trough in the Wednesday night-Thursday time
frame, amplifying and elongating the trough from SW-NE. Ultimately
the building ridge to our north will cause the increasingly
enlongated trough to split Saturday, with the northern split lifting
northeast while the southern split looks to retrograde into the
Central GOM. This will hopefully result in the tropical moisture
plume being reoriented west of the area by Sunday-Monday with mid-
lvl ridging then building into the eastern CONUS in that time
period.
In terms of sensible weather, the main concern will remain the
flooding potential Thursday/Friday as the lingering tropical
moisture will interact with upper-lvl disturbances pivoting through
the base of the trough. Although raw totals don't look quite as high
as the initial surge on Tuesday/Wednesday (although they could be
comparable over SEFL) it is possible the ground will be already
saturated from the earlier week rainfall, so any additional heavy
rainfall could exacerbate hydro issues. Consequently, assuming the
Tues/Wed rainfall more or less pans out as expected, the flood watch
will likely need to be extended into the Thursday/Friday timeframe.
Assuming the aforementioned synoptic evolution occurs, Saturday will
hopefully mark the end of the heavy rainfall threat, as the
retrograding trough and building ridge combination should direct the
deep tropical moisture to our west. Although lingering low-lvl
moisture will support at least scattered showers and storms through
the period, the strengthening easterly flow and building heights
should limit the chances for widespread heavy rainfall beyond Friday
night/early Saturday (although exact forecast details remain
uncertain).

Poor flying conditions at times during the 12Z TAF period as deep
tropical moisture results in periods of heavy rain and
thunderstorms. Prevailing MVFR ceilings is expected with
occasional IFR/LIFR ceilings and visibilities during periods of
heavy rain. Southerly winds around 10 kts however winds will be
erratic in and near thunderstorms.

.MARINE...
Issued at 152 AM EDT Tue Jun 11 2024
Periods of strong showers and thunderstorms are expected over the

hazardous winds and seas. Outside of thunderstorms, cautionary-
level (at time near hazardous) south-southwesterly winds can be
expected through Wednesday with seas 3 ft or less.
