Irma is moving toward the southwest Florida coast as a major hurricane.
Conditions will continue to deteriorate as the center of the storm
moves closer to the area, and a period of damaging winds with gusts to
hurricane force is still expected late this afternoon and into early
The large wind field associated with the storm will produce far-
reaching effects well to the east of the center. Tropical storm force
wind gusts between 50 to 60 mph are being reported along the Space and
Treasure Coasts, and these winds will continue to spread inland and to
the north through the day. Hurricane force wind gusts between 75 to 90
mph in squalls will remain a significant concern as they become more
frequent and intense throughout the day.
The threat for tropical rain band tornadoes continues to increase. A
Tornado Watch is in effect for all of east central Florida until
The potential for flooding rain associated with repeated squalls will
increase across east central Florida through the afternoon. Several
areas south of Orlando and Cape Canaveral have already picked up
between 2 and 4 inches of rainfall, especially along the Treasure and
Space Coasts. Although Irma will be moving steadily northward, it will
produce an additional 6 to 10 inches of rain across the region, with
locally higher amounts up to 16 inches. This is likely to cause
significant, widespread urban and lowland flooding, as well as
potentially causing inundation of major highways, and both secondary
and residential roads.
Additionally, localized wind driven water inundation remains a concern
across areas adjacent to larger inland lakes such as Lake Okeechobee,
Lake Kissimmee, and Lake George, as well as the Intracoastal Waterway.
NOW IS THE TIME TO REMAIN IN YOUR SAFE SHELTER! Residents and visitors
to east central Florida are strongly encouraged to monitor the latest
products issued by your local National Weather Service Office.
Impacts from the main wind event will be unfolding today! Remain well
sheltered from dangerous winds. Prepare for significant, widespread
damaging wind gusts across east central Florida. These impacts include:
- Considerable roof damage to sturdy buildings, with some having
window, door, and garage door failures leading to structural
damage. Mobile homes severely damaged, with some destroyed.
Damage accentuated by airborne projectiles. Locations may be
uninhabitable for weeks.
- Many large trees snapped or uprooted along with fences and
roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. Several bridges, causeways, and
access routes impassable.
- Large areas with power and communications outages.
* FLOODING RAIN:
Impacts from the flooding rain will continue to spread north today!
Remain well guarded against life-threatening flood waters having
extensive impacts. Prepare for life-threatening rainfall flooding
having possible extensive impacts across east central Florida. These
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, and ditches may
become dangerous rivers. Flood control systems and barriers may
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.
Prepare for a dangerous tornado event having possible significant
impacts. These include:
- The occurrence of scattered tornadoes can hinder the execution
of emergency plans during tropical events.
- Several places may experience tornado damage with a few
locations seeing considerable damage, power loss, and
- Locations could realize roofs torn off frame houses, mobile
homes demolished, boxcars overturned, large trees snapped or
uprooted, vehicles tumbled, and small boats tossed about.
Dangerous projectiles can add to the toll.
Prepare for locally hazardous surge having impacts from Flagler Beach
to Jupiter Inlet. These include:
- Localized inundation with storm surge flooding mainly along
immediate shorelines and in low-lying spots, or in areas
farther inland near where higher surge waters move ashore.
- Sections of near-shore roads and parking lots become overspread
with surge water. Driving conditions dangerous in places where
surge water covers the road.
- Moderate beach erosion. Heavy surf also breaching dunes, mainly
in usually vulnerable locations. Strong rip currents.
- Minor to locally moderate damage to marinas, docks, boardwalks,
piers, and other coastal structures. A few small craft broken
For those who have evacuated to safer shelter, do not return to any
evacuated areas until hazardous winds diminish and flood waters abate.
During the peak of the storm, keep your shoes on and your rain gear
handy. Boots and athletic shoes offer the best foot protection if
you become unexpectedly exposed to the weather.
