Icons displayed with reduced opacity correspond to occurrences whose nature is:

• Fuel Management
• Burning
• Burn Prevention

• (FWI) Fire Weather Index - This is the final Canadian index system, calculated based on the sub-indexes ISI and BUI.
• (FFMC) Fine Fuel Moisture Code - This index classifies the fine fuel moisture regarding moisture percentage. It is related to the degree of flammability of the fuel located at surface level. The moisture percentage at 12 UTC for a given day, depends on the moisture percentage at the same time the precious day, 24 hours (12-12 UTC) precipitation (mm), temperature (ºC) and relative humidity (%) at 12 UTC that day. Wind speed affects only the drying speed of the material.
• (ISI) Initial Spread Index - This index classifies the inicial propagation of the fire. It depends on the sub-index FFMC and wind speed (km/h) at 12 UTC.
• (BUI) Build Up Index - The build up index, is a index of evaluation of the vegatation that is able to feed a fire ("heavy" fuel on the ground). It is calculated from two sub-indexes: DMC e DC.
• (DC) Drought Code - This index translates de moisture percentage of the húmus and medium sized firewood materials located below surface up to 8 cm. It is calculated from the precipitation for 24 hours (12-12 UTC), temperature e relative humidity at 12 UTC and DC the previous day.
• (DMC) Duff Moisture Code - This index is a good index of the effects of seasonal drought on forest fuel (húmus and large sized firewood materials), located below surface, from 8 to 20 cm deep. The index is calculated from precipitation from the previous 24 hours, temperature at 12 UTC and drought code the previous day.

The RCM (Risco Conjuntural e Meteorológico) combines the FWI with the territorial hazard map. It is not the FWI — it is an integrated index, computed per municipality, and the official indicator used in public alerts.

RCM is split into five classes:

• Low
• Moderate
• High
• Very High
• Maximum

Whenever this layer is active on the map, its colour legend shows in the bottom-left corner.

More info at IPMA — Rural Fire Danger.

On top of the incident icons, the main map can show several optional layers, toggled from the "Map" panel (top right). What each layer means and what the icons stand for:

Satellite hotspots (MODIS, VIIRS, IPMA FRP)

Hotspots detected from space in the last few hours. MODIS (Aqua/Terra) and VIIRS (Suomi NPP / NOAA-20) come from NASA FIRMS; "IPMA FRP" is the Fire Radiative Power product from LSA-SAF, refreshed every 15 minutes. A hotspot is not a fire confirmation — any thermal anomaly (wildfire, volcano, factory, controlled burn) can show up. Useful for spotting active fires visible from space.

Lightning strikes

Strikes detected by the IPMA network over the last 24 hours. Colour encodes amplitude polarity; size encodes the strike type.

• Negative strike (cloud-to-ground) — usually more energetic and more likely to ignite fires.
• Positive strike (cloud-to-ground).
• Intracloud strike — drawn smaller and dimmer.
• Older strikes fade out (≤1h opaque, then 1–6h, 6–12h, 12–24h progressively more transparent).

Satellite events (Gaia)

Available on the /gaia view. Red markers = active satellite-detected events; grey = inactive. Click an event to load its current footprint polygon; the "Ver evolução" button opens an animated timeline of the historical perimeter.

Animated wind

Particles drifting through the wind field forecast by IPMA's AROME model (u/v components at 10 m, current hour). The local intensity in km/h shows in the bottom-right corner while the cursor is over the map.

Point value for IPMA layers

With any IPMA forecast layer on (temperature, wind, humidity, precipitation, wind direction), clicking or tapping the map shows the layer's value at that point in the bottom-right corner. The query hits the same AROME model used to render the layer.

At the bottom of every incident page there is a map with two satellite-derived products provided by FOCO (Fire Observation and Characterisation Observatory, from VOST Portugal): the current fire perimeter and a 6-hour spread simulation. The Meteosat Third Generation (MTG) product is generated every 10 minutes; the block only appears when satellite data is associated with that incident.

Perimeter (red polygon)

Traces the area the Meteosat Third Generation (MTG) satellites are seeing with enough radiated energy. Each satellite pixel is 2 to 4 km wide over Portugal; FOCO clusters the recent FRP (Fire Radiative Power, in megawatts) detections and draws a polygon around them. This is not the official ICNF burned-area figure (compiled after the fact); it is a near-real-time view of where the fire is currently releasing energy.

Spread (isochrones +1 h to +6 h)

The concentric rings show how far the fire could reach in each of the next 6 hours, hour by hour. It is a minimum-travel-time simulation (Dijkstra's algorithm on a 100 m grid) that combines: the reference rate of spread calibrated for Portugal (PyroCast), the IPMA wind forecast (a directional exponential multiplier that speeds up the head fire and slows the flanks), the terrain slope (Copernicus GLO-90 DEM — spread rate roughly doubles for every 10° of upslope, following McArthur's empirical law), and the fuel moisture (dead-fine-fuel moisture, DFMC, is the dominant factor; above ≈30% fire barely progresses). On the map, the isochrones animate hour by hour.

What it is for

This is situational-awareness information. The perimeter helps you gauge how much is actually burning right now; the simulation helps anticipate what lies in the fire's path — villages, roads, infrastructure — over the coming hours. The block also carries the list of affected municipalities and parishes, computed by spatial intersection with DGT's CAOP 2025. The badge under the title shows the time of the last processed satellite pass.

Complements — never replaces. Important caveats.

FOCO is not a nascent-fire detector: a 1 or 2 hectare fire rarely reaches the energy threshold (50–100 MW) needed for the satellite to see it. Fires typically only show up on MTG once they escape initial attack and grow. In short: fogos.pt detects the dispatch (the fire may still be small); FOCO detects the actual radiated energy — they are complementary. The simulation is a heuristic envelope, not a forecast: it does not model spotting (flying embers), active suppression or pyroconvection; it assumes the forecast wind — a sudden shift or a passing front can drive the real behaviour away from the modelled scenario. Fires mostly on the Spanish side of the border show up as "Outside simulation coverage" because the fuel-load rasters only cover mainland Portugal. These products never replace the ANEPC, IPMA or ICNF official channels.

Data provided by FOCO — VOST Portugal, based on the LSA SAF MTG MTFRPPixel product (EUMETSAT, hosted at IPMA), PyroCast (VOST) for rate of spread and fuel moisture, COS2023 (DGT) for land cover and fuel load, Copernicus GLO-90 DEM for terrain slope, and CAOP 2025 (DGT) for the municipality and parish boundaries.

Every incident has an IPMA forecast panel for the exact fire location. Hourly weather variables (next 48 h) are fed by the AROME model. The FWI and the Canadian sub-indices are computed at 12 UTC from the ECMWF model — not from AROME. The LSA-SAF products (daily, 7 days) combine satellite observation with ECMWF forecasts. The dashed red vertical line marks the current hour.

• Temperature and humidity — air temperature at 2 m (°C, left axis) and relative humidity (%, right axis). Key dryness indicator: humidity below 30% combined with high temperatures accelerates fire spread sharply.
• Wind and gust — mean wind intensity at 10 m and peak gust (km/h). Arrows on top show direction: the arrow head points to where the wind is blowing.
• Atmospheric pressure — sea-level pressure (hPa). Sharp variations may signal an approaching or passing weather front.
• Accumulated precipitation — forecast precipitation accumulated over one hour (mm). Useful to gauge relief or worsening on the ground.
• FWI / ISI / BUI — Canadian fire weather indices, computed at 12 UTC from the ECMWF model. FWI is the final composite; ISI captures initial spread; BUI captures available fuel. Higher = more dangerous.
• DC / DMC / FFMC — fuel moisture indices. DC tracks deep fuels (long-term drought), DMC mid-layer, FFMC fine surface fuels (fast response to recent weather).
• FRM — extremes probability (%) and anomaly (%) against climatology. Flags atypical conditions for the time of year.

The RCM (Risco Conjuntural e Meteorológico) — equivalent to the Rural Fire Danger — has no dedicated chart on this page; it is shown as a layer on the main map, with its own legend.
