NEW INFORMATION ---------------

* STORM INFORMATION:     - About 300 miles south of Orlando FL or about 250 miles       south-southwest of Vero Beach FL     - 24.1N 81.5W     - Storm Intensity 130 mph     - Movement Northwest or 325 degrees at 8 mph
SITUATION OVERVIEW ------------------
Dangerous and large Category 4 Hurricane Irma is moving northwest and approaching the lower Florida Keys early this morning. The eye of Irma will cross the Keys later this morning and then turn north-northwest and move near and roughly parallel to the Florida Gulf Coast through tonight as a major hurricane. Irma is forecast to remain a hurricane as it moves toward north Florida and the panhandle on Monday afternoon.
As Irma continues to march northward, its very large and damaging wind field will produce far-reaching effects well to the east of the center. Hurricane force wind gusts in squalls will remain a significant concern as they become more frequent and intense overnight and throughout the day across all of east central Florida. Sustained winds at or very near hurricane force, with higher gusts, are expected to spread north along the Kissimmee River basin, and then into Lake County through tonight.
The increased threat for tropical rain band tornadoes from Lake Okeechobee and Tequesta through Osceola and Brevard Counties will continue to expand northward across the greater Kissimmee-Saint Cloud, Orlando, Sanford, Daytona and Leesburg areas today and tonight.
A Tornado Watch remains in effect for east central Florida from Osceola and Brevard Counties southward until noon today. Watches are very likely to be extended farther north by late morning.
The high potential for flooding rain associated with repeated squalls will spread northward today, tonight. 2 to 4 inches of rain had fallen across many locations along the east coastal counties, and south of Orlando, with local amounts of 6 to as much as 11 inches over some portions of the Treasure Coast. As Irma continues to move northward, it produce an additional 6 to 10 inches of rain across the region, with locally higher amounts of 15 to 20 inches, especially over the Treasure Coast Counties of Indian River, Saint Lucie, and Martin.
This is likely to cause urban and lowland flooding ranging from significant to locally extreme. Inundation of major highways, and both secondary and residential roads is expected or will be aggravated where it is already occurring.
Potentially life threatening seas and surf will continue today into Monday as large wind and swell waves bring dangerously high seas and surf and increasingly strong rip currents. Moderate to significant beach erosion will continue, becoming progressively worse through Monday, especially around the times of the next few high tide cycles. The next high tides will occur along the east coast around 1130 AM this morning, near midnight tonight, and 1230 PM Monday afternoon.
Do not venture onto beachfront areas! Small craft should remain in port until winds and seas subside!
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.
POTENTIAL IMPACTS -----------------
* WIND: 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 include:     - 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       become stressed.     - 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.
 * TORNADOES: 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       communications failures.     - 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.
* SURGE: 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
 PRECAUTIONARY/PREPAREDNESS ACTIONS ----------------------------------
* EVACUATIONS: For those who have evacuated to safer shelter, do not return to any evacuated areas until hazardous winds diminish and flood waters abate.
If sheltering in place, during the peak of the storm, keep sturdy shoes on and rain gear handy. Boots and tennis shoes offer the best foot protection if you become unexpectedly exposed to the elements.
Continue to keep your cell phone well charged for as long as possible. If you lose power, use it more sparingly and mainly for personal emergencies and check-ins.
If a Tornado Warning is issued for your area, be ready to move to an safe, interior room away from windows on the lowest floor of your residence. Put as many sturdy walls between you and the storm as you can. Protect your head and body.
If a Flood Warning is issued for your area, be ready to take appropriate action to protect life and property. Avoid venturing near streams, water retention areas, and other poorly drained low lying areas. Don't drive onto flooded roads.
Do not be a senseless thrill seeker or risk your life for photos or videos!! Be wise and avoid becoming another statistic.
Closely monitor NOAA Weather Radio or other local news outlets for official storm information. Listen for possible changes to the forecast.
