MadeiraOcean
Read full descriptionHide full description
MadeiraOcean app (in experimental phase) was created with the purpose of displaying graphically the results of COAWST (Coupled Ocean Atmospheric Wave Sediment Transport) model, implemented by the Oceanic Observatory of Madeira for Madeira Archipelago. Although the model is regularly validated, it is difficult to guarantee the accuracy of the presented data, as forecasts are predictions and should be considered as such. In this app you can check the forecasted data for air and water temperature, direction and speed of currents, waves and tides, plus precipitation, winds and atmospheric pressure. All these variables are available for more than 30 points around the island, with forecasts for every three hours. Additionally, the satellite data presented in this app come from the Copernicus Marine Service (https://resources.marine.copernicus.eu/). The products are: Temperature: SST_GLO_SST_L4_NRT_OBSERVATIONS_010_001 Chlorofill a: OCEANCOLOUR_ATL_CHL_L4 NRT_OBSERVATIONS_009_037

Riska — wildfires, weather and official warnings for the places you care about in Portugal, all year round. INDEPENDENT APP — NOT A GOVERNMENT SERVICE Riska is not operated by, affiliated with, or endorsed by any government entity including ANEPC, IPMA, ICNF, SGIFR or APA. It aggregates publicly available data from the sources listed below and does not generate data independently. Information may be delayed or incomplete. In an emergency, follow official authorities and call 112. ONE MAP, ALL YEAR - Wildfires: Civil Protection (ANEPC) and ICNF incidents with their official status, source and time. Satellite detections (NASA FIRMS) are shown separately, as unconfirmed. - Winter (mainland Portugal): incidents recorded by Civil Protection — fallen trees and structures, landslides and road occurrences (they do not mean a road is closed) on the map; flooding reported to ANEPC in the list, by municipality — always with time and source. - APA flood zones: official long-term flood mapping (100-year return period). It does not show flooding in progress. - Official IPMA warnings by district (wind, rain, snow, cold, rough seas), including those that start later. - IPMA fire danger by municipality. Official information is always shown separately from Riska's own analysis. RADAR AND FORECAST — WITH A FREE ACCOUNT - Rain radar (EUMETNET OPERA), with the time of every image and a legend. - Rain, snow and cloud forecasts from the ECMWF model for the coming days. Every image shows its time. When data is late, the app tells you. NEARBY - Save the place you care about — your home, your land, your family's village — and see what is happening around it: incidents, warnings and weather. A free account includes one saved place. - Weather at your place and a forecast for the coming days, with the source and time of every reading. ALERTS THAT EXPLAIN WHY - Alerts when an incident, an official warning or a fire-danger peak meets your place — by notification, email or Telegram — with the distance to your place where it applies. - Follow an incident to get alerts about it. Alerts are supplementary awareness: they can be delayed and do not replace official warnings. COMMUNITY PHOTOS Photos are displayed publicly only with the sender's permission and moderator approval.
