At 300 AM MDT (0900 UTC), the center of Tropical Depression Norma
was located near latitude 24.5 North, longitude 108.4 West. The
depression is moving toward the east near 7 mph (11 km/h) and this
motion is expected to continue until dissipation occurs later today
or tonight. On the forecast track, the center of Norma is forecast
to move inland along the coast of the Mexican state of Sinaloa later
this morning.
Maximum sustained winds have decreased to near 35 mph (55 km/h)
with higher gusts. Little change in strength is expected before
Norma reaches the coast of Mexico. Weakening and dissipation is
anticipated once Norma moves inland.
The estimated minimum central pressure is 998 mb (29.47 inches).
