If you are trying to connect different parts of the weather puzzle, this is a must-see site. Has hundreds of models and links for everything from sea-surface temps to earthquakes and El Nino.
MyFloodRisk.org Goes beyond traditional flood maps which may be outdated. Looks at risk from a number of other perspectives to give you a much more accurate assessment. Also includes a “Probable Damage Calculator” that lets you input the value of your home and contents. It then calculates the likely amount of damage you could expect for each inch of floodwater you get. Extremely powerful and simple to use site.

Floodplain Maps and Elevation:
City of Houston Water Flood Hazards Maps flood hazard extents for many smaller streams and ditches in neighborhoods that are not covered in other maps that focus mainly on river flooding.
ElevationMap.net. Check the elevation of your home or wherever you are standing. Works on geographic coordinates or allows you to input an address.
FEMA Estimated Base Flood Elevation Viewer Shows not only the extent but also the estimated depth of floods. Maps many areas not included in the National Flood Hazard Layer Viewer. See below.
FEMA National Flood Hazard Layer Viewer. Zoom into any part of the country. Wait a few seconds. And outlines for the floodway and 100-year flood plain will appear. This website has amazing investigative potential. With it, you can tell how far your home, business or sand mine is from flood threats.
FEMA Flood Map Service Center – Plug in any address and instantly see where you the property stands in relation to floodplains that may exist around it.
Flood Exposure and Other Mapping Tools. This particular tool is geared toward coastal areas but also covers all of Harris County. It includes FEMA’s flood hazard layers, plus dozens of other visualization tools, all in one website. Shows development density, wetlands, emergency infrastructure, and much, much more. Lets you vary opacity of different layers and save maps.
FloodMap.net. Enter an elevation (in meters) above current sea level to see what areas would be inundated by a flood of that height. See how floodwaters spread or recede as you increase or decrease the height. Helps visualize why some areas flood and others don’t.
Flood Decision Support Toolbox – A Texas Water Development Board/USGS site. Click on a river gage, select a flood depth, and see how far the waters would spread. Clicking on a location within the flooded area will also show you the estimated depth at that point. You can also turn on a layer that shows flooded buildings. Unfortunately, however, the number of gages is limited, and most are in northern Harris and southern Montgomery Counties.
Harris County Flood Control Flood Education Mapping Tool. Has fewer options, but is easier to use. Contains great list of FAQs related to flooding and flood insurance. For instance, did you know that of the 2500 miles of channels and streams in Harris County, only 1300 have mapped flood plains? It’s important to understand the limitations of this and similar tools.
MAAPnext. Harris County Modeling, Assessment and Awareness Project (MAAPnext) is developing the next generation of flood mapping, Flood Insurance Rate Maps (FIRMs), and new tools for communicating flood risk. Will improve management and regulation of Harris County’s floodplains through better understanding.
MyFloodRisk.org. Input your address and it will tell you the elevation of your slab, your base flood elevation and calculate the difference for you. Contains many other powerful functions also. Together, they will give you a much more accurate assessment of risk than simple flood maps.
National Weather Service Inundation Viewer. Select a gage, then click on Inundation tab. Then select a flood level in the left hand column and click on any point in the flood zone. A pop up box will show you how much water you could expect to get at that location for the given gage height.
The Harvey Story in Montgomery County An interactive GIS (geographic information system) site by ESRI focusing on flood damage in Montgomery County Texas. Also includes flood damages from Memorial Day, Tax Day and 1994 floods. Zoom into any part of the county and see exactly how many homes flooded there.
