AIR MAIL

Where today’s air came from

The air arriving over Juana Díaz about 5,000 feet above the ground was over the tropical Atlantic three days ago, and over the Caribbean a day ago, about 860 miles back along its path. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK IN 2003 Nov. 13–14, 2003

The wettest two days this week has seen

8.90 inches of rain fell in two days, the most for this week of the year since records began in 1898. The next wettest, 7.00 inches, fell in 1909.
