...Above Normal Rainfall Persisted Into October 2017 Across East
Central Florida...

A wet pattern continued into October, with locally heavy rainfall
that was extreme at times, especially along the coast. This led to
additional flooding issues that were magnified by already soaked
ground conditions following a September that was one of the wettest
on record, due to Hurricane Irma. These periods of heavy rainfall
produced totals that were well above normal for much of the area,
except inland, north of Okeechobee County, where precipitation was
closer to normal for the month. Temperatures remained above normal
through much of October until a couple stronger cold fronts moved
through the area late in the month. Despite this significant cool
down toward the end of October, overall average temperatures still
ended up near to above normal across the region.


...Temperatures...

Despite a couple weak fronts that moved through the area during
early to mid October, temperatures generally remained above normal.
Highs typically ranged in the mid to upper 80s, occasionally
reaching the low 90s across the interior. Overnight lows continued a
trend this year of being much warmer than normal, with values often
in the mid to upper 70s. These values tied or broke numerous warm
minimum temperature records at climate sites across the region (see
full list below).

The first strong cold front of the season moved across central
Florida late on the 24th. Highs the following couple days didn`t
rise above the low to mid 70s, and lows fell into the 50s and 60s
across most areas. This was the first time temperatures fell below
70 degrees for many locations since late May to mid June of this
year. Also, this front ended a record streak of days at Melbourne
where the high reached 80 degrees or above, totaling 199 days since
April 9th (previous record was 192 consecutive days, ending on
November 14th in 2015). An even stronger cold front followed on the
29th, with lows dropping into the 40s and highs in the mid to upper
60s on the 30th. These cooler temperatures tied or broke a few
record cool highs across the area that day.

If not for the significant cool down at the end of the month,
monthly average temperatures were poised to rank this October as one
of the warmest on record! However, the colder temperatures,
especially behind the second stronger front, dropped average
temperatures for the month drastically, with only Melbourne and
Sanford ranking within their respective top 10 warmest values.

...Rainfall...

October 2017 started off quite wet, especially for Brevard County,
when persistent heavy rain bands north of a stalled front moved
onshore on the 1st, producing rainfall up to 4 to 7 inches, with
locally excessive amounts up to 8 to 10 inches in some areas of the
county. Melbourne broke their rainfall record that day, receiving up
to 5.23 inches. This heavy precipitation produced flash flooding,
with several roadways becoming impassable and water entering some
homes. Continued onshore flow and deep moisture in place produced
high rainfall coverage, locally heavy in some places along the coast
and into Okeechobee County through the 5th.

Sea breeze collisions led to higher coverage of showers and a few
storms over inland areas during the 6th through 8th of the month.
Then a more predominant high pressure ridge north of the area
maintained an onshore flow for much of mid October, leading to
scattered light to moderate showers moving onto the coast and inland
through this period. An additional locally heavy rainfall event
occurred along the Volusia County coast from the 17th to 18th, as a
surge in northeast flow behind a weak front produced persistent rain
bands that generated amounts up to 2 to 4 inches.

Additional heavy rainfall occurred with a strong cold front that
moved through the region late on the 24th, as well as with poorly
organized Tropical Storm Philippe that moved across south Florida
early on the 29th. Greatest rainfall totals associated with moisture
from Philippe occurred across Okeechobee County, the Treasure Coast
and extreme southern Brevard County, where 2 to 4 inches of
precipitation were common. As another strong cold front then moved
through the region, shifting Philippe away from the area, much drier
air moved into central Florida keeping the area rain-free for the
end of the month.

Overall, rainfall totals for October were highest across the coastal
counties and Okeechobee County with totals ranging between 8 to 15
inches, or roughly 4 to 8 inches above normal! Most notable was
Melbourne and Stuart where precipitation this October ranked within
their respective top 5 wettest. Farther inland from Osceola County
northward through Lake County, rainfall totals were generally near
normal ranging from 2 to 4 inches for the month.
