A live lightning map, a national weather-station network, an interactive Forecast Hub with plain-language risk tiers, a Sargassum Outlook, a hurricane-season scorecard, and community-level flood maps you can compare year to year – all in one place, all the time.
For years, the rhythm has been the same. The rain sets in, the wind picks up, the rivers start to rise – and everyone refreshes Facebook, WhatsApp, and Instagram, waiting for someone to post an update. When the update finally comes, it is often a single image, already a few hours old, that may or may not mention your part of the country.
The weather is happening to you now, so the information should be at your fingertips, not locked behind a social media post you have to wait for and hope someone shares.
As we head into the 2026 Wet Season, the Trinidad and Tobago Weather Center has rolled out a suite of connected live, self-serve tools. You don’t have to wait for us to push them out. You can open them yourself anytime and zoom straight to your area.
Here is what’s new.
⚡ See lightning as it strikes – the Live Lightning Map
Thunderstorms are the defining hazard of our wet-season afternoons, and lightning is the part that hurts people. Until recently, the only way to know if a storm was electrically active near you was to look outside and count the seconds.
Our new Live Lightning Map shows where lightning is striking across Trinidad and Tobago, and it updates continuously. It is built on satellite-based lightning detection (NOAA’s GOES-19 Geostationary Lightning Mapper), broken down into our 35 forecast zones, so you can see which part of the country is “lighting up” right now.
You can step back through the last 30 minutes, hour, or up to 24 hours with the time scrubber, watch a storm’s electrical intensity build and fade, and read off a live count of recent flashes by zone. There’s a lightning-safety reminder built right into the panel, because when thunder roars, go indoors.
🌡️ “What about my area?” – the Weather Station Network
The most common question we get during extreme weather is exactly that: what about my area? The honest answer used to be that we could only report the few stations whose data we could see, and they were rarely the one down your street.
So we built a national observation network. As of June 2026, TTWC is compiling publicly available data from 160+ weather stations, air-quality monitors, and rainfall/streamflow gauges across the country, including official networks operated by the Trinidad and Tobago Meteorological Service (TTMS), the Environmental Management Authority (EMA), and the Water and Sewerage Authority – Water Resources Agency (WRA), alongside trusted personal weather stations.
Here’s the whole network at a glance – every station we track, mapped:
That same data powers two live dashboards anyone can open. Current Conditions shows temperature and heat index, rainfall, wind and gusts, pressure, and air quality station by station; switch between current values and the day’s high or low; and tap any station for the full breakdown. River Levels shows live gauge readings on our flood-prone rivers against each river’s capacity, so you can see whether a watercourse near you is running high before it spills.
All of it lives on our Observations hub:
Our Live Dashboards
🗺️ The Forecast Hub – and what our Risk Tiers actually mean
A forecast is only useful if you can find yourself in it. Our 3-Day Weather Outlook (the Forecast Hub) lets you search for your own community – all 587 of them – and see the top hazards for your zone over the next three days, day by day, with any active, official early warning alerts from the Trinidad and Tobago Meteorological Service layered right on top.
What sets the Hub apart is how it communicates risk. The TTMS uses a four-color system: Green, Yellow, Orange, Red. That works, but a single “Yellow” can cover everything from a bit of street ponding to genuinely dangerous flooding. So TTWC uses a six-tier system that gives you finer resolution and tells you, in plain language, both how likely an impact is and how bad it could be:
These tiers aren’t arbitrary. They were calibrated against 850+ TTMS Early Warning Messages issued between 2018 and 2026, and each step up is anchored to a real event Trinbagonians remember – so “Extreme” rainfall, for example, means the scale of October 2018, not just “a lot of rain.” We also reserve the top tiers for genuinely rare conditions, so when you see them, they mean something.
🌊 The Sargassum Outlook – for the coast, and the people who use it
Sargassum is the other side of our marine season. Since 2011, mats of this floating seaweed have been washing onto Trinidad and Tobago’s beaches – Matura, Manzanilla, and Speyside among the hardest hit – and once it piles up and starts to rot (roughly two days after it lands), it gives off hydrogen sulfide: the rotten-egg smell that can genuinely affect people with asthma and anyone living right along the coast. The sargassum season runs March through September, heaviest from May to August – squarely inside our Wet Season.
So we built a 3-day Sargassum Outlook that works like the Forecast Hub, but for the coastline. Search your beach or coastal community and see what’s expected over the next three days on its own interactive map – split into what’s likely to wash ashore (nearshore) and what mariners and fishers will meet out on the water (open water).
It runs on a five-tier scale anchored to NOAA’s Sargassum Inundation Risk product, the same plain-language colors as our weather risk tiers, from No Risk through Very High, and it treats the coast and the open sea differently. Nearshore tiers speak to beaching: how much seaweed there is, how deep it is, the odor, and when it’s best to stay out of the water or away from the shore. Open-water tiers speak to navigation and fishing: fouled gear, clogged motor intakes, and reduced visibility, because offshore, sargassum is actually valuable habitat for turtles and juvenile fish, not just a nuisance.
🌀 The hurricane season forecast – but how right is it?
Every year since the mid-2010s, the TTMS issues a seasonal hurricane outlook, and for 2026 the call is a below-average to near-normal season for our region. Useful, but a forecast you can’t check is just a number.
So we built a tool that keeps score. Our Tropical Cyclone Activity tracker plots 76 years of storm activity inside Trinidad and Tobago’s Area of Interest (1950–2025), with the 1991–2020 averages drawn in for context (about 3.6 named storms and 1.1 hurricanes in our box each year). Then it overlays the TTMS seasonal forecasts on top, and, crucially, tells you whether each year’s forecast verified: a ✓ when the season landed inside the predicted range, an ✗ when it didn’t.
In other words: you can judge the forecast for yourself, year by year, instead of taking anyone’s word for it — ours or theirs.

💧 Flood Risk Potential – finally, a map you can actually use
This is the one we’re proudest of.
Each year since 2021, the TTMS issues a Flood Risk Potential (FRP) Outlook – a community-by-community assessment of how this Wet Season’s flood risk compares to a typical year. It is genuinely valuable work. But for most of its life, it reached the public as a single static image, shared once, with little to no follow-up. If you didn’t catch the post, you missed it. Even if you did, it was nearly impossible to tell whether your community was flagged or how this year stacked up against the last one.
We’ve turned that one image into something you can use. Our interactive Flood Risk Potential map lets you search your community (or let it find you), tap your area, and read off exactly which risk band it falls in this year – for all 587 communities across Trinidad and Tobago.
And because risk only makes sense in context, the map remembers every year since 2021. Tap your community, and its full history opens up, so you can see whether your outlook has eased or worsened – and spot the bigger pattern, like 2024 standing out as the most severe outlook on record, more than double any other year.
Comparing year to year matters because flood risk isn’t static – it tracks the climate signals behind each season (El Niño / La Niña, Atlantic Ocean temperatures, the hurricane outlook). Seeing those shifts is how a community moves from surprise to preparedness.
(Data: TTMS · Visualization: TTWC. The FRP Outlook is a seasonal-potential assessment, not a forecast of specific flood events from the Trinidad and Tobago Meteorological Service.)
It’s all in one place – so you don’t have to wait
Put together, these tools change the deal. You no longer have to wait for an image to land in a group chat to know what’s happening. When the sky darkens, you can open the lightning map. When the rain sets in, you can watch the rivers and check your community’s forecast. Before the season even starts, you can see how your flood risk compares to last year — and decide for yourself how seriously to take the hurricane outlook.
That’s the whole point: your weather, on demand.
Bookmark the Observations hub, keep the Forecast Hub close, and let us know if you operate a weather station and want to contribute to the network of stations – the more eyes on the sky, the better we all see it coming.
