    DISCUSSION AND OUTLOOK
    ----------------------
    At 400 AM CDT (0900 UTC), the center of Tropical Storm Isaias was
    located near latitude 22.0 North, longitude 94.1 West. Isaias is
    moving toward the east-northeast near 8 mph (13 km/h). A continued east-northeastward motion is expected today, followed by a turn
    toward the northeast and north on Thursday and Friday. On the
    forecast track, Isaias is expected to pass to the north of the
    Yucatan Peninsula on Thursday and approach the U.S. northern Gulf
    Coast on Friday.

    Maximum sustained winds have increased to near 40 mph (65 km/h) with
    higher gusts. Rapid strengthening is forecast over the next day or
    two, and Isaias is expected to become a hurricane by Thursday.

    Tropical-storm-force winds extend outward up to 45 miles (75 km)
    from the center.

    The estimated minimum central pressure is 1004 mb (29.65 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Isaias can be found in the Tropical Cyclone
    Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.

    RAINFALL: Isaias is expected to produce rainfall amounts of 2 to 4
    inches through Thursday across coastal portions of the Bay of
    Campeche with isolated higher amounts possible in the states of
    Campeche and western Yucatan.

    From Friday through the weekend, Isaias is expected to produce
    rainfall amounts of 3 to 6 inches, with localized totals up to 10
    inches, across the northern U.S. Gulf Coast extending from far
    southeastern Louisiana to the Florida Panhandle. Rainfall amounts of
    1 to 3 inches, with localized amounts up to 5 inches, are possible
    across much of the Southeast as far north as the Tennessee Valley
