Interactive Weather Map (wxMap)
The Interactive Weather Map is one of the new features for Intellicast.com. We are continuously modifying and improving features of the Interactive Weather Map. There may be occasional disruptions of service during updates, but they are generally short in duration.

Please let us know what you think of this product by filling out our Interactive Weather Map feedback form.


Command View

Command View is our new Beta version of the Intellicast Interactive Weather Map. We are currently working on new and simpler ways for users to access their favorite weather layers and information. By clicking on the WeatherVIEW button, our new WeatherVIEW box will show the current conditions and today's forecast for the location at the center of the map. This feature will stay on the map until you click the close button in the upper right hand corner of the WeatherVIEW. If you have any questions, comments or feedback, please let us know.


NowNet™

Many of the layers available on the WeatherActive Map are created using our exclusive NowNet data collection and analysis system. This unique processing technique merges meteorological data from weather observation stations, sophisticated computer models, high definition terrain/elevation data, and other meteorological sources to create highly detailed and accurate representations of various weather parameters.

NowNet Temperature

WeatherActive’s NowNet Temperature layer, which shows in vivid detail contours of current temperatures, is perhaps the most dramatic example of the value of this advanced approach. If you live in a mountainous region or along the coast you know that the weather report from a nearby town or airport may not represent your location particularly well. For example, in the Denver, Co area it is quite common to have local temperatures routinely vary as much as 20 degrees or more on a typical day usually due to elevation differences. By integrating all of the various inputs from NowNet, the Intellicast WeatherActive Map is able to show the local variation of temperatures with astonishing accuracy.

NowNet Wind Speed

Wind speed is often a highly localized event and wind speeds tend to be greater in data sparse areas such as over large water bodies or high up in the mountains where there are few weather sensors. By supplementing routine surface observations with computer models and elevation information, NowNet is able to portray wind speed in a far more accurate manner than previously seen in conventional wind reports. If you are a sailor, you know that the winds offshore, where there are few weather reporting stations, are often much higher than in port. In the example below a developing Nor’easter along the New England coast is causing dangerously windy weather offshore.

NowNet Snow Cover

Ever wonder how much snow is actually on the ground somewhere? Every hour NowNet processes a variety of snowfall related parameters to determine how much snow has recently fallen, how much snow was already on the ground, and how much snow has melted, to create a highly accurate view of the current snow pack. This is a great tool to plan winter getaways or estimate what the spring snow melt may have in store for your area.

Road Weather Index (Beta)

The WSI Road Weather Index is an approximation of where weather that has occurred over the past 2 hours may be contributing to hazardous driving conditions at this moment in time. The Road Weather Index uses a simple 6 category classification system; each category highlights a specific road hazard such as “icy” roads. The index is set up in a hierarchical manner based on the assumption that some hazards are more dangerous than others. For example, an area may be both “foggy” and “icy” at the same time, in such a situation the index would default to show “icy” since it is generally perceived as a more threatening condition. The index is updated every 15 minutes. Remember, this product reflects what is going on now and is not a forecast of what might happen later. In addition, the index does not account for weather events which occurred over 2 hours ago such as snow or ice covered roads which have not been plowed or treated for some time.

Using the Road Weather Index Layer
Layers List In the top right-hand corner of the interactive weather map, click the "Layers" button to expand a list of layer types (see example to the right). Find "Road Weather Index" and click it to select the layer. You will now see color coded areas on the map representing the road weather index for the visible area. Use the "Roads" legend to see which index category corresponds to each color.

The index categories include (in hierarchical order):

  Windy Areas where sustained winds may be high enough to impact high profile vehicles
 
  Foggy Areas where visibility due to fog or precipitation may be significantly limited
 
  Wet Areas where roads are probably wet from recent rainfall and may be slippery
 
  Puddles Areas where recent rainfall may be causing “ponding”, puddles, or localized flooding
 
  Snowy Areas where snow is either falling or has recently fell and may impede driving
 
  Icy Areas where recent icing has been observed or is likely occurring resulting in slippery roads

The Road Weather Index uses a combination of surface observations, radar imagery, sophisticated computer simulations, and an understanding of terrain elevation to make its determination. The index currently covers the immediate continental United States and some portions of both Mexico and Canada which are in very close proximity to the U.S. border.

It is important to understand that this index is based on certain meteorological observations which may at times not be sufficient to properly identify all road hazards. Also, this index has no knowledge of whether a specific road has been treated with chemicals or plowed. For more specific road conditions many state and provincial department of transportation web sites offer more detailed road condition reports and advisories.

Base Map Options

Base maps represent how the earth appears under the weather layers. Currently, the interactive weather map offers two types of base maps. More base map options will be added as they are developed.

Changing Base Maps
Base Map List In the top right-hand corner of the interactive weather map, click the "Base Map" button (to the left of the "Layers" button) to expand a list of base map types (see sample list to the right). Select the map you want by clicking on a base map name in the list.

Map options include:

Known Issues

Browser Compatibility
If you are using certain browsers such as Google Chrome or Microsoft Internet Explorer 8, you may have trouble displaying or using the interactive weather map. We are working to maximize compatibility for these and other browsers. We recommend using Internet Explorer 6 or 7, Firefox, or Safari when using the interactive weather map.

Saving Maps
There is currently an issue with adding and removing saved maps. Sometimes maps that you have removed can show up in the saved map list again, and maps you have added may tend to disappear from the saved list. We are working to fix this bug and should have it resolved very soon.

Periodic Maintenance Page
We will put up a maintenance page during our maintenance periods. This will happen periodically, but usually for a short duration. If you are sent to this page, try visiting the interactive weather map again in a few minutes.

Missing Weather Data Tiles
Occasionally some of the tiles used to represent the weather may not be available at certain zoom levels or parts of the world. When this happens the location of the missing tile will show a generic 'empty-tile' and small alerts at the bottom of the map will indicate the error. This is the current expected behavior of the Interactive Weather Map when the data is unavailable.
