See the whole forecast on your locations map

Product updates

The Locations map can now show every kind of weather data LMKwhen alerts you on — not just the warnings that are already active, but the forecasts and outlooks that feed your rules. Open the Layers panel on the map to turn them on.

Heavy rainfall and winter outlooks​

The Weather Prediction Center's Excessive Rainfall Outlook — the best advance signal for flash flooding, often flagging a Moderate or High risk a day or two before any Flash Flood Watch — now draws on the map in the official WPC colors, Days 1 through 5. Alongside it, the winter precipitation probability outlooks show the chance of plowable snow or damaging ice, out to Day 7.

Both work like the SPC outlooks you already know: pick a day, click a shaded area to see what it is.

Every forecast field you can build a rule on​

All twenty gridded forecast products are now viewable, grouped by what they are:

  • Temperature & Heat — Heat Risk, WBGT, high and low temperature, apparent temperature
  • Winter — 72-hour snowfall, ice accumulation
  • Wind — sustained wind, wind gusts
  • Precipitation — total precipitation, chance of precipitation
  • Humidity — minimum and maximum relative humidity
  • Tropical — wind, storm surge, flooding rain and tornado threat, plus tropical wind probabilities

If you have a rule watching wind gusts, you can now look at the wind gust forecast on the same screen as the properties it covers.

Each layer has a Valid control for stepping through the forecast — hour by hour for wind and WBGT, day by day for high and low temperature — and every layer carries the National Weather Service's own color scale, so what you read on the map is exactly what the forecasters published.

Hurricane tracks and cones​

Turn on any of the Tropical layers and you can overlay the National Hurricane Center forecast track and cone of uncertainty for every active system, with the advisory positions marked. The threat grids show you what the storm could do to a place; the cone shows you where the storm is expected to go.

Filter the map by collection​

The collection filter is now multi-select. Tick two collections and you see both — useful when you manage several regions and want to look at just the Gulf Coast and the Southeast together, without the rest of your portfolio on screen. It works from the list view toolbar and from the map's own Layers panel, and the filter travels in the page address, so you can bookmark a view or send it to a colleague.

Step through today's hazards​

When anything in your account is alerting, a bar appears at the bottom of the map listing each hazard behind it — a tornado warning, an enhanced severe risk, a heat exceedance — one stop per weather layer.

Step through them with the arrows, or press play and the map walks itself through them, 30 seconds each with a countdown to the next. Each stop shows that hazard on its own and moves the map to fit the properties it is affecting, so you see both the weather and whose site is under it.

The map never switches layers on by itself. It opens exactly as you left it and waits for you.

Forecast layers now default to a lighter 40% opacity so your properties and any active warnings stay readable on top of them. You can adjust it with the Opacity slider whenever a layer is turned on.
