The Baltimore Sun: “In a potential sea change for a nautical industry heavy on tradition, the National Oceanic and Atmospheric Administration’s recent National Charting Plan suggested that, eventually, ‘the reduction or elimination of traditional paper nautical charts seems likely.'” (This is NOAA looking into the future, but note that private companies, rather than NOAA, already do the printing and distributing of paper charts; NOAA’s charts are, of course, available online and can be printed.)

While the map shows the historical probability that a snow depth of at least one inch will be observed on December 25, the actual conditions in any year may vary widely from these because the weather patterns present will determine the snow on the ground or snowfall on Christmas day. These probabilities are useful as a guide only to show where snow on the ground is more likely.
While the subject may seem whimsical, it’s based on 1981-2010 Climate Normals data; this paper details into the methodology involved. (It also answers a question that climatologists and meterologists get a lot.)
Start with the National Hurricane Center, which has lots of different maps of Hurricane Matthew’s predicted path, weather warnings, rainfall potential and so forth. See also maps from Weather Underground.
Google’s Crisis Map includes evacuation resources—Red Cross shelters, evacuation routes, traffic data—in addition to storm track and precipitation information.
Jason-3 is the latest earth observation satellite tasked with measuring global sea surface height; its data will be used in weather and climate research (e.g., El Niño, climate change). Launched on January 17, it’s now in its six-month checkout phase and has produced its first complete map, which corresponds well with the map produced by the still-operational Jason-2 satellite, so that’s a good sign.

According to analyses by NASA and NOAA scientists, 2015 was the warmest year on record, with average surface temperatures the highest they’ve been since 1880. The above video shows the long-term warming trend since 1880 as a five-year rolling average. The baseline average is from 1951 to 1980; orange colours are warmer than that average, blue colours cooler. (Credit: GSFC Scientific Visualization Studio.)
