SHOWERS AND THUNDERSTORMS EXPECTED TO IMPACT SOUTH FLORIDA
TERMINALS THIS EVENING AND INTO THE EARLY MORNING HOURS ON
SATURDAY. THE MOST IMMEDIATE IMPACTS WILL BE FOR TERMINAL KAPF. AN
ACTIVE AREA OF THUNDERSTORMS IS DEVELOPING ABOUT 20 MILES WEST OF
KAPF OVER THE GULF WATERS AND STEADILY MOVING NORTHEAST AND RECENT
RADAR RETURNS HAVE INDICATED FUNNEL CLOUDS POSSIBLE WITH THIS
ACTIVITY. ANOTHER ACTIVE AREA OF SHOWERS AND THUNDERSTORMS IS
ACROSS THE MIDDLE KEYS AND MOVING STEADILY NORTH ALONG OUTFLOW
BOUNDARIES. ALTHOUGH TIMING WILL BE TOO DIFFICULT TO
ESTIMATE...ALL SOUTH FLORIDA TERMINALS COULD HAVE BRIEF PERIODS OF
IFR CONDITIONS THIS EVENING AND INTO EARLY SATURDAY MORNING. TAF'S
WILL BE AMENDED AS CONDITIONS WARRANT.

.PREV DISCUSSION... /ISSUED 250 PM EDT FRI OCT 28 2011/

SHORT TERM...
SCATTERED SHOWERS CONTINUE ACROSS THE REGION...WITH LIGHT TO
MODERATE RAIN NORTH OF THE REGION. MOSTLY CLOUDY TO CLOUDY SKIES
WERE SEEN ACROSS THE REGION. THE MID/UPPER LEVEL CIRCULATION FROM
RINA WILL MOVE ACROSS SOUTHERN AND SOUTHWESTERN FLORIDA
TONIGHT DUE TO THE STRONG SOUTHWEST FLOW ALOFT. IN ADDITION...A
COLD FRONT WILL BE PUSHING SOUTH ACROSS THE STATE. SO PERIODS OF
HEAVY RAIN WILL BE POSSIBLE...ESPECIALLY ALONG THE GULF COAST. THE
HEAVIEST RAINFALL MAY SET UP ACROSS CENTRAL/SOUTHWEST FLORIDA AND
THE NAPLES REGION OVERNIGHT BEFORE MOVING INTO THE REST OF SOUTH
FLORIDA ON SATURDAY. WIDESPREAD 1 TO 3 INCHES OF RAIN IS EXPECTED
TONIGHT THROUGH SATURDAY NIGHT ACROSS THE REGION...WITH LOCALLY
HEAVIER AMOUNTS. SO PONDING ON ROADWAYS AND LOCALIZED FLOODING IS
POSSIBLE.

THE COLD FRONT IS EXPECTED TO PUSH INTO THE FLORIDA KEYS OR
FLORIDA STRAITS SATURDAY NIGHT...BUT LOW LEVEL MOISTURE IS
EXPECTED TO REMAIN IN PLACE. SO LIGHT STRATIFORM RAIN IS POSSIBLE
SATURDAY NIGHT BEHIND THE FRONT. THE WINDS SHIFT BACK TO THE EAST
AGAIN ON SUNDAY...PUSHING MOISTURE BACK ACROSS THE REGION. MODELS
ARE SHOWING DECENT ISENTROPIC LIFT ALONG THE OLD FRONTAL
BOUNDARY...SO EXPECT A CHANCE FOR RAIN ACROSS THE EAST COAST.
HIGH TEMPERATURES ARE EXPECTED TO BE IN THE UPPER 70S TO AROUND 80
DEGREES.

LONG TERM...
ANOTHER ENERGY IMPULSE WILL DIG RAPIDLY SOUTH TO SOUTHEAST U.S. BY
MONDAY INDUCING A SOUTHERLY FLOW AHEAD OF IT ALLOWING THE FRONT TO
BEGIN TO DRIFT BACK NORTH ACROSS SOUTH FLORIDA. WL INDICATE A
CHANCE OF SHOWERS MON AND MONDAY NIGHT. HOWEVER...THIS SAME SHORT
WAVE WILL FINALLY PUSH THE FRONT SOUTHEAST OF THE AREA BY TUESDAY
WITH DRIER AND SLIGHTLY COOLER CONDITIONS WED THROUGH THURSDAY. &&

AVIATION...FOR 18Z TAFS
AN ORGANIZED AREA OF RAINFALL AND EMBEDDED THUNDERSTORMS OVER THE
EASTERN GULF OF MEXICO CONTINUES TO SLOWLY PUSH TOWARD THE REGION.
IN ADVANCE OF IT, SCATTERED SHOWERS ARE FORMING IN THE
INCREASINGLY UNSTABLE ENVIRONMENT OVER MAINLAND SOUTH FLORIDA. WE
EXPECT CONVECTION TO CONTINUE TO DEVELOP THROUGH THIS EVENING,
ALTHOUGH THE MOST WIDESPREAD PRECIPITATION WILL LIKELY HOLD OFF
UNTIL OVERNIGHT OR EARLY SATURDAY NEAR THE EAST COAST. AT KAPF,
HEAVIER PRECIPITATION WILL ARRIVE AROUND 00Z. BRIEF MVFR CEILINGS
AND VISIBILITIES ARE EXPECTED THROUGH TONIGHT. IFR CONDITIONS WILL
ALSO BE POSSIBLE SATURDAY MORNING, ALTHOUGH TIMING REMAINS
SOMEWHAT UNCERTAIN. WHILE A FEW TSRA ARE EXPECTED, FOR NOW WE WILL
CARRY JUST VCSH AND A CB REMARK IN THE TAFS, GIVEN THE ANTICIPATED
COVERAGE.

MARINE...
LIGHT WINDS SHOULD PREVAIL THROUGH TONIGHT, BUT SHOULD BEGIN
VEERING TO THE SOUTH AND SOUTHWEST BY SATURDAY MORNING OUT AHEAD
OF A COLD FRONT. WILL WILL SHIFT TO THE NORTH AND INCREASE RAPIDLY
TO ADVISORY CRITERIA SATURDAY AFTERNOON/EVENING AS THE FRNT MOVES
TROUGH. MODERATE TO STRONG NORTH/NORTHEAST WINDS ARE EXPECTED TO
CONTINUE THROUGH SUNDAY.

FIRE WEATHER...
MOISTURE LEVELS WILL REMAIN WELL ABOVE CRITICAL LEVELS THROUGH
PERIOD. PERIODS OF HEAVY RAIN ARE POSSIBLE TONIGHT THROUGH THE DAY
ON SATURDAY ACROSS SOUTH FLORIDA AS A COLD FRONT MOVES THROUGH THE
REGION.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TONIGHT

TORNADOES: A BRIEF TORNADO OR WATERSPOUT CANNOT BE RULED OUT ACROSS
SOUTH FLORIDA AND THE ADJACENT WATERS TONIGHT. THE MOST FAVORABLE

WIND SHEAR SLOWLY INCREASES THROUGH THIS EVENING. THIS THREAT IS
MINIMAL BUT JUST CANNOT BE RULED OUT AT THIS TIME.

THUNDERSTORMS: A FEW THUNDERSTORMS WILL BE POSSIBLE. THE STRONGEST
STORMS WILL BE CAPABLE OF PRODUCING OCCASIONAL LIGHTNING STRIKES AND
LOCALLY HEAVY RAINFALL ESPECIALLY AFTER MIDNIGHT. A BRIEF TORNADO
CANNOT BE RULED OUT.

FLOODING: THERE WILL BE AN INCREASING THREAT OF LOCALLY HEAVY
RAINFALL LATE TONIGHT ACROSS THE REGION WHICH MAY LEAD TO MINOR URBAN
STREET FLOODING.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

A FEW THUNDERSTORMS ARE POSSIBLE ACROSS SOUTH FLORIDA ON SATURDAY
AHEAD OF A COLD FRONT. THE PRIMARY IMPACTS WILL BE OCCASIONAL LIGHTNING
STRIKES AND LOCALLY HEAVY RAINFALL. SOME OF THE STRONGER
THUNDERSTORMS COULD PRODUCE LOCALLY HEAVY RAINFALL WHICH COULD
LEAD TO SOME MINOR URBAN STREET FLOODING.

WINDS AND SEAS WILL BE ON THE INCREASE SATURDAY NIGHT AND SUNDAY
IMMEDIATELY BEHIND THE WEAKENING COLD FRONT, RESULTING IN HAZARDOUS
MARINE CONDITIONS...ESPECIALLY ACROSS THE GULF STREAM OFF THE PALM
BEACH COUNTY COAST. THE RISK OF RIP CURRENTS ALONG THE ATLANTIC
BEACHES WILL ALSO BE ON THE INCREASE LATE THIS WEEKEND AND
POSSIBLY INTO THE FIRST PART OF NEXT WEEK.

Event by event

4 flash flood, 1 thunderstorm wind. Local standard time, as filed.

Flash Flood, Broward

When: October 28, 9:00 PM EST to October 29, 1:00 AM EST
Where: Broward County, 5.08 mi WSW of Coral Spgs to 2.25 mi NW of Coral Spgs
Cause: Heavy Rain
Reported by: Emergency Manager
Coordinates: 26.236, -80.293

Torrential rainfall occurred in northwestern metro Broward County, with 5-7 inches of rain falling in less than 6 hours. These extremely high rain rates led to significant flooding of many streets in the Coral Springs, Coconut Creek and Parkland areas. Roads were closed in Coral Springs and there were several reports of stalled vehicles. Canals overflowed in Coral Springs, but despite the amount of surface flooding, very few reports of structural flooding were received.

Flash Flood, Palm Beach

When: October 28, 9:00 PM EST to October 29, 1:30 AM EST
Where: Palm Beach County, 5.81 mi WSW of Boca Raton to 0.67 mi W of Delray Beach
Cause: Heavy Rain
Reported by: Emergency Manager
Coordinates: 26.328, -80.171

Rainfall amounts of 6 to 9 inches fell over southeastern Palm Beach County in less than 6 hours, leading to numerous reports of flooded streets and some road closures. No reports were received of water entering structures, but water was deep enough to close maintained roads and threaten structures.

Flash Flood, Miami-Dade

When: October 30, 7:30 PM EST to October 31, 4:00 PM EST
Where: Miami-Dade County, 1.28 mi NNE of Goulds to 4.23 mi S of Pinewood
Cause: Heavy Rain
Property damage: $100,000
Reported by: Law Enforcement
Coordinates: 25.567, -80.371

Severe flooding occurred over large parts of eastern metro Miami-Dade County beginning during the evening hours of October 30th and continuing well into the next day. The area of heavy rain began over southern sections of the flood area, including Cutler Bay, Palmetto Bay and Key Biscayne around 830 PM EDT and spread north to the Pinecrest, Coral Gables and Coconut Grove areas around 10 PM EDT, and from city of Miami to North Bay Village shortly after midnight. Numerous roads were under deep water and reports of dozens of homes with water intrusion were received across this entire area.

Rainfall amounts were in the 6 to 10 inch range across this area, virtually all of it falling in less than 12 hours. Highest rainfall estimates were in Coconut Grove where up to 12 inches or more may have fallen, causing water to pond to as high as 4 feet in a few areas. A Coral Gables PD official deemed this to be the most flooding he's ever seen in the area. The western half of Key Biscayne was under water.

Thunderstorm Wind, Miami-Dade

When: October 30, 7:40 PM EST
Where: Miami-Dade County, 1.06 mi W of Cutler Ridge
Measured: 56 kt (64 mph) estimated gust
Reported by: Public
Coordinates: 25.581, -80.347

Public estimated 65 mph winds in Cutler Bay. This wind may have been associated with a tornadic thunderstorm just offshore over Biscayne Bay.

Flash Flood, Broward

When: October 31, 1:00 AM EST to 4:00 PM EST
Where: Broward County, 0.94 mi ENE of Plantation to 1.28 mi NE of (Fxe)ft Laudrdl Exec
Cause: Heavy Rain
Property damage: $2.0 million
Reported by: Emergency Manager
Coordinates: 26.084, -80.185

Torrential rainfall affected eastern sections of metro Broward County during the overnight hours of October 31st. Rainfall totals of 8 to 12 inches occurred over an area bounded by I-595 to the south and Pompano Beach to the north, from NW 31 Ave to the west all the way to the Atlantic coast. A few spots in this area likely received amounts close to 15 inches in about a 9-hour time span. These rains fell over areas already saturated from the rains of the previous two days. A total of 402 homes were affected by water damage and streets were closed due to inundation in Fort Lauderdale, Oakland Park, Wilton Manors and Pompano Beach. The area hardest-hit was between Broward and Commercial Boulevards between I-95 and Federal Highway where water covered the ground up to a few feet.

The city of Fort Lauderdale opened a shelter for displaced residents in the hardest-hit areas. These areas qualified for federal assistance due to the magnitude and areal coverage of the flooding.

Damage amounts listed here are estimated by emergency managers taking into account total number of damaged properties and SBA loans.

What these are

Flash Flood: Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
Thunderstorm Wind: Winds from a thunderstorm of 50 knots (58 mph) or more, or lower winds that caused damage or casualties. Measured gusts are marked MG, estimated EG.

After NWS Directive 10-1605, the rules offices file Storm Data by.
