As of early on Aug. 30, Hurricane Dorian has
been producing 2 to 6 inches of rain along the path of its inner core
for several days. This estimate come from the NASA IMERG algorithm,
which combines observations from a fleet of satellites, in near-real
time, to provide global estimates of precipitation every 30 minutes. The
total rainfall at a particular location varies with the forward speed
of the hurricane, with the size of the hurricane’s wind field, and with
how vigorous the updrafts are in the hurricane’s eyewall. The graphic
also shows the distance that tropical-storm force (39 mph) winds extend
from the Hurricane Dorian's low-pressure center, as reported by the
National Hurricane Center. The symbols H2, H1, and TS represent category
2 hurricane, category 1 hurricane, and tropical storm, respectively.
