Alternative Text Description for Moderate High Tide Flooding (NOAA)

TABLE OF CONTENTS

MAP OVERVIEW

This map displays areas along the Florida coastline that are vulnerable to moderate high tide flooding according to NOAA data. The map identifies coastal zones where moderate flooding occurs during high tide events, showing the geographic extent of areas at risk from this type of tidal inundation. The thematic layer highlights the spatial distribution of moderate high tide flooding hazards across Florida's extensive shoreline.

GEOGRAPHIC CONTEXT

The map covers the state of Florida and portions of neighboring states including southern Georgia and Alabama. Major cities labeled on the map include Pensacola in the western panhandle, Tallahassee in the north-central region, Jacksonville along the northeast coast, Orlando in central Florida, Tampa and St. Petersburg on the west coast, Cape Coral on the southwest coast, and Miami in the southeast. The map extends from Albany, Georgia and Dothan, Alabama in the north to the Florida Keys in the south. The geographic context includes both the Gulf of America coastline along Florida's west and panhandle shores and the Atlantic Ocean coastline along the east. Neighboring cities such as Valdosta, Georgia, Gainesville, Florida, Palm Coast, Lakeland, Melbourne, Palm Bay, Port St. Lucie, and Coral Springs are also labeled to provide additional spatial reference points.

KEY INSIGHTS

Moderate high tide flooding vulnerability is concentrated along Florida's immediate coastal areas, with particularly notable patterns in several key regions. The western panhandle shows extensive flooding extents around Pensacola and along coastal areas stretching eastward toward Tallahassee. The Big Bend region of Florida's Gulf coast, where the panhandle meets the peninsula, displays a continuous band of moderate flooding zones. Along Florida's Atlantic coast, significant flooding extents appear near Jacksonville and continue southward along coastal communities including Palm Coast. The Tampa Bay metropolitan area shows concentrated flooding vulnerability, as does the southwestern coast near Cape Coral. The southeastern coast from Miami through the Florida Keys exhibits extensive moderate high tide flooding zones. Interior portions of the state show no flooding vulnerability, with all affected areas confined to immediate coastal zones and low-lying shoreline communities.

VISUAL ELEMENTS

Moderate High Tide Flooding Layer

This layer represents areas along Florida's coastline that experience moderate flooding during high tide events as identified by NOAA.

Extent of Moderate HTF (bright cyan/turquoise areas)

Appearance:

The affected areas are displayed in bright cyan or turquoise coloring against a light gray base map, creating clear contrast between flooded and non-flooded zones.

Distribution:

The flooding extents appear along the entire perimeter of Florida's coastline, including both the Gulf of America and Atlantic Ocean shores, with varying widths of coastal penetration.

Notable locations:

Spatial patterns:

The flooding zones follow linear coastal patterns, closely hugging shorelines, bays, estuaries, and tidal waterways. The extent typically penetrates inland only in narrow bands along immediate coastal areas, with deeper penetration visible in low-lying coastal zones and areas around bays and inlets. The pattern reveals that moderate high tide flooding is confined to immediate coastal geography rather than extending into interior regions.

Overlapping Patterns

No overlapping patterns are present as this map displays a single thematic layer showing moderate high tide flooding extents.

SYMBOL GUIDE

ADDITIONAL INFORMATION

This map focuses exclusively on moderate high tide flooding zones and does not display other flooding categories or severity levels that may exist in NOAA's data. The map provides a regional overview of Florida's coastal flooding vulnerability and is intended to show broad geographic patterns rather than parcel-level detail. Users should understand that moderate high tide flooding represents a specific category of tidal flooding and that other flooding types or severity levels may also affect these or other areas. The visualization emphasizes the linear coastal nature of high tide flooding risk and demonstrates how Florida's extensive coastline creates widespread vulnerability to this type of flooding event.

DATA CONTEXT

Data Source:

The data originates from the National Oceanic and Atmospheric Administration (NOAA), which collects and analyzes tidal flooding data based on observed tide levels, coastal topography, and flooding frequency patterns. The source layer is identified as NOAA_HTF_MODERATE.

Definition Query:

No definition query or filter criteria was applied to this dataset. The map displays the full extent of moderate high tide flooding zones as provided in the source data.

Scale Information:

The map is displayed at a regional scale appropriate for viewing the entire state of Florida and portions of neighboring states. This scale level is suitable for understanding broad geographic patterns of coastal flooding vulnerability but is not intended for site-specific or parcel-level analysis.

Coordinate System:

The map uses the NAD 1983 HARN Florida GDL Albers projection (WKID 3087), which is optimized for displaying geographic data across the state of Florida with minimal distortion.

Time Period of Content:

The specific time period for data collection is not provided in the available information.

Limitations:

Information about data gaps, specific methodological limitations, or areas not mapped is not available in the provided information. Users should consult NOAA documentation for detailed information about how moderate high tide flooding extents are determined and any limitations in data coverage or accuracy.

Map Coverage:

The map extends from the Florida-Georgia and Florida-Alabama borders in the north to the southernmost Florida Keys, encompassing the entire Florida peninsula and panhandle. Portions of southern Georgia and southeastern Alabama are included to provide geographic context. The map shows all of Florida's Gulf of America and Atlantic Ocean coastlines.
