* CHANGES TO WATCHES AND WARNINGS:     - The Hurricane Watch has been upgraded to a Hurricane Warning       for Volusia, Lake, Orange and Seminole Counties
* CURRENT WATCHES AND WARNINGS:     - A Hurricane Warning and Storm Surge Watch are in effect for       Coastal Volusia County     - A Storm Surge Warning and Hurricane Warning are in effect for       Indian River, Martin, Northern Brevard County, Southern Brevard       County, and St. Lucie     - A Hurricane Warning is in effect for Inland Volusia County,       Northern Lake County, Okeechobee, Orange, Osceola, Seminole,       and Southern Lake County

SITUATION OVERVIEW ------------------
Dangerous Hurricane Irma continues to move west-northwest along the north coast of Cuba. Irma is expected to turn toward the north- northwest later today and then cross the Florida Keys as an intense hurricane early Sunday morning. Irma is forecast to move north and reach the southwest Florida coast Sunday evening as a strong hurricane, and then move northward across the western peninsula through early Monday morning.
Irma is a large hurricane and will produce far-reaching effects regardless of where the exact center of the storm moves. Winds of strong tropical storm to Category 1 hurricane force, especially in gusts, are expected to produce considerable damage well east of Irma's track, extending across east central Florida.
There remains a significant threat for flooding rains, and a Flood Watch continues for all of east central Florida. Heavy rain, especially in squalls, will increase in coverage and frequency across east central Florida tonight, and especially on Sunday through early Monday. Although Irma will be moving steadily northward, it will produce 8 to 12 inches of rain with locally higher amounts of 15 to 20 inches in areas which receive frequent or persistent squall bands.
Efforts to protect life and property should be rushed to completion! Every effort should be taken to bring hurricane preparations to completion by sunset today.
A storm surge of around 3 feet on top of local tidal ranges can be expected. Some wind driven water inundation will be possible in areas immediately adjacent to larger inland lakes, such as Lakes Okeechobee, Kissimmee, and Lake George, as well as the Intracoastal Waterway.
Ahead of Irma, surf conditions will become hazardous as large swells bring high surf and increasingly strong rip currents. Beach erosion will ensue, and become progressively worse during the next several high tide cycles from early Sunday morning through Monday morning.
The threat for tornadoes within frequent squall bands will increase beginning late tonight around Lake Okeechobee and Tequesta, spread northward across Osceola and Brevard Counties through sunrise, then across the remainder of east central Florida throughout Sunday.
 POTENTIAL IMPACTS -----------------
* WIND: Protect against life-threatening wind having possible extensive impacts across east central Florida. Potential impacts include:
    - Considerable roof damage to sturdy buildings, with a few having       window, door, and garage door failures leading to structural       damage. Mobile homes severely damaged, with some destroyed.       Damage accentuated by airborne projectiles.     - 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. Some access routes impassable.     - Large areas with power and communications outages.
* FLOODING RAIN: Protect against life-threatening rainfall flooding having possible extensive impacts across east central Florida. Potential impacts 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: Protect against a dangerous tornado event having possible significant impacts across east central Florida. Potential impacts 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: Protect against locally hazardous surge having possible impacts from Flagler Beach to Jupiter Inlet. Potential impacts in this area 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       away from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS ----------------------------------
* EVACUATIONS: If evacuating, leave with a destination in mind and allow extra time to get there. Take your emergency supplies kit. Gas up your vehicle ahead of time.
* OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Outside preparations should be wrapped up as soon as possible before weather conditions deteriorate. Any remaining evacuations and relocations should be completed before the onset of tropical storm force winds.
It is important to remain calm, informed, and focused during an emergency. Be patient and helpful with those you encounter.
If you are in a place that is vulnerable to high wind, such as near looming trees, a manufactured home, upper floors of a high rise building, or on a boat, consider moving to safer shelter before the onset of tropical storm force winds or possible flooding from heavy rain.
If a tornado warning is issued for your area, be ready to shelter quickly, preferably away from windows in an interior room on the lowest floor. If driving, scan the roadside for quick shelter options. Have a way to receive tornado warnings whether on the road or in a shelter.
Closely monitor weather.gov websites, NOAA Weather Radio, or other local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.
