This Year's Rainfall
Anchorage's cumulative rainfall so far this year against its own record — the normal accumulation, and the wettest & driest years to date. The bright line is the running total; where it rides the band tells the story at a glance.
Anchorage's entire daily record as one heatmap — each row a year, each cell a day, shaded by that day's rainfall. Dry spells read as dark blocks, wet seasons as brighter bands; the whole climate at a glance.
Every week of the U.S. Drought Monitor for Anchorage's county since 2000, coloured by intensity — dry spells and multi-year droughts read as warm bands.
