DISCUSSION AND OUTLOOK
———————-
At 300 PM GMT (1500 UTC), the center of Hurricane Isaac was located
near latitude 43.2 North, longitude 35.6 West. Isaac is moving
toward the northeast near 12 mph (19 km/h) and this motion is
expected to continue during the next couple of days, followed by a
turn toward the north-northeast on Tuesday.
Maximum sustained winds have decreased to near 75 mph (120 km/h)
with higher gusts, and continued weakening is forecast over the next
few days. Isaac is forecast to become a post-tropical cyclone on
Monday.
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 205 miles
(335 km).
The estimated minimum central pressure is 971 mb (28.68 inches).
HAZARDS AFFECTING LAND
———————-
SURF: Swells generated by Isaac and an upstream deep-layer trough
will affect the Azores over the next few days. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
