Last week, #California had some extreme fire activity. Here is the #BridgeFire and the #LineFire hotspots animated over the most active days. Explore for yourself: lens.pathandfocus.com/?endDa…

Wanna see something cool? We (@calebissharp) built a fire simulation model... in Rust... and it's blazing fast... also it outputs ASCII (for fun). This dynamically pulls weather data, topography, fuel, runs a 12h burn period producing a 18,700ha fire all in 6 seconds. #wildfire

Looking at #wildfire data often requires that you know exactly when a fire took place. It doesn't help you interact with or explore unfamiliar data. Mother Nature just doesn't care about the fact that it's Saturday. 🗓️ Let's break down how we can do better. 🧵

We're adding historic @CWFIS hotspot data to lens.pathandfocus.com and have noticed that the estimated size leans a particular way in certain regions at certain times of the year. E.g. in S.E. USA the est size is larger in later months. Anyone have ideas why?

Lens is a map of Canadian wildfire data created by @pathandfocus + @twostoryrobot Explore wildfires interactively by date and area - built with a static set of pmtiles archives lens.pathandfocus.com @pwramsey might find it interesting!

I often describe fire growth as a series of "sprints". It's not a steady jog, but rather large amounts of growth occurring in short timeframes. @twostoryrobot's hot spot tool provides a great visual representation of this with the count of spots per day.

Last week, a cold front passed through the province following several days of hot, dry weather.

We're experimenting with visualizing all the hotspot data at once. In case you were wondering what #Yellowknife is facing right now, here's all hotspots this year (grey) with the last 3 days in yellow, orange, and red. Scary stuff. Stay safe up there friends.

Let me introduce you to a new term I’ve started using… “tactical recreation” #wildfire in BC is now just a part of life, and we have to adapt. Keep a bag of gear ready and monitor air quality regularly. If it’s green nearby, bug out to breath some clean outside air.

This one is the best of the afternoon. Really fluid stuff! It looks like it just kinda erupts. #wildfire #bcwildfire #kamloops

Scary weekend with that #osoyoosfire. It took only a matter of hours for it to grow substantially and threaten hundreds of homes. lens.pathandfocus.com/?zoom=…

We've been working on adding evac alert/order boundaries to Lens (our experimental mapping tool). While the WMS tile layers are convenient, we'd prefer the polygon data. Also, we're noticing the gov service is giving errors frequently (probably lots of demand).

Some more #wx #dataviz! Last week I explored fire weather for some select stations in BC. Today I want to explore why two stations a mere 4km apart have such vastly different danger ratings.

I spent the weekend playing with the #bcwildfire @BCGovFireInfo #wx data. It’s a bit cumbersome but not impossible. Here is a quick guide on how you can download this weather data for yourself, merge all the files into one, and filter it to just show noon data. 🧵
