Inland Flooding impacts:
The Inland Flooding impacts detailed in this WFOís Inland Flooding Graphics are not associated with riverine flooding. Specific river observations and river stage forecasts in this WFO's area of responsibility are available from their Advanced Hydrologic Prediction Service (AHPS) web site, at: Tampa Bay, Florida
None Threat - No discernible threat to life and property; but rain possible.

Minimum Action - Listen for forecast changes; review flooding safety rules.

Potential Impact - Brief heavy rain may still occur but flooding is not expected.

Low Threat - An elevated threat to life and property with rain totals causing isolated minor problems.

Minimum Action - Gather loose belongings in yard, drive carefully and donít drive through water of unknown depths.

Potential Impact - Residents can expect nuisance flooding of roads with poor drainage. Ponding of water on roads will occur elsewhere. Known intersections with very poor drainage may have water levels up to 2 feet. Other poor drainage areas will have water rises up to 1 foot. Urban and Small Stream Flood Advisories may be needed.

Moderate Threat - A significant threat to life and property with areas of flooding entering homes and buildings.

Minimum Action - Gather loose belongings in yard, drive carefully and donít drive through water of unknown depths. Evacuate if necessary.

Potential Impact - Residents can expect areas of flooding, especially in poor drainage locations. In these areas, minor to moderate property damage is expected, and several main thoroughfares may be closed. Known intersections with very poor drainage may have water levels up to 4 or 5 feet. Other poor drainage areas will have water rises up to 3 feet. Most small streams and creeks will reach or exceed bank full. Larger rivers will rise. Those rivers that respond quickly to very heavy rain may briefly exceed flood stage. Fire ants, snakes, and alligators will likely be in flooded areas.

High Threat - A critical threat to life and property with Widespread flooding, having major impact on buildings with road closures.

Minimum Action - Gather loose belongings in yard. Driving will be hazardous if not impossible. Evacuate only if necessary.

Potential Impact - People living near or in poor drainage locations should prepare for possible evacuation. In these areas, significant property damage will occur, and some power outages are likely. Minor property damage is possible elsewhere. Water levels in very poor drainage areas will approach 7 feet. Other poor drainage locations will have rises to between 3 and 5 feet. Elsewhere, expect water rises to near 2 feet. Numerous main roads will be closed. Driving is highly discouraged except in emergencies. All rivers in affected areas will rise, with some reaching or exceeding flood stage. Normally quick rising rivers will exceed flood stage by several feet, flooding homes along the shore. Pastures will also flood, but livestock losses should be minimal. Fire ants, snakes, and alligators will likely be in flooded areas. Several secondary roads and bridges will be washed out.

Extreme Threat - An extreme threat to life and property with catastrophic flooding: Neighborhoods inundated; numerous road closures.

Minimum Action - Gather loose belongings in yard. Driving will be hazardous if not impossible. Evacuate only if necessary.

Potential Impact - Widespread Catastrophic Flooding Possible! Residents in flood prone areas should rush to completion preparations to protect their property, then move to a place of safety. Mandatory evacuations are underway in flood prone locations. Life threatening flooding is likely. In urban areas, extensive property damage will occur in all poor drainage areas, with moderate to major property damage elsewhere. Widespread power outages are likely. In rural locations, all small streams and creeks will surpass bank full for more than 6 hours. Each will exceed their banks by several feet, flooding homes - even those up to one half mile away from the banks. In all areas, hundreds of roads will flood. Dozens of secondary roads may become washed out in rural areas. Numerous bridges will likely wash out as well. Water levels will exceed 5 feet in all poor drainage urban areas...and average at least 2 feet elsewhere. All rivers in affected areas will rise; most will exceed flood stage. Quick rising rivers will exceed flood stage - and reach near record crests, causing inundation of nearby homes. In rural locations, extensive pasture flooding will occur as water levels rise to 2 feet or more. Widespread livestock losses are likely. Fire ants, snakes, and alligators will likely be in flooded areas.
