DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), the center of Tropical Storm Cristobal was
located by an Air Force Reserve reconnaissance aircraft near
latitude 28.2 North, longitude 89.9 West. Cristobal is moving toward
the north near 12 mph (19 km/h) and this general motion is expected
to continue today, followed by a gradual turn toward the
north-northwest late today or tonight.  On the forecast track, the
center of Cristobal will approach the northern Gulf of Mexico coast
this afternoon, then move inland across Louisiana late today through
Monday morning, and northward across Arkansas and Missouri Monday
afternoon into Tuesday.

Data from NOAA Doppler weather radars indicate that maximum
sustained winds remain near 50 mph (85 km/h) with higher gusts.
Little change in strength is forecast before landfall, and weakening
will begin once Cristobal moves inland.

Tropical-storm-force winds extend outward up to 205 miles (335 km)
mainly to the east of he center.  A National Ocean Service station
at the Southwest Pass of the Mississippi River recently reported a
sustained wind of 43 mph (69 km/h) and a gust to 51 mph (82 km/h) at
an elevation of 78 feet (24 m).

The minimum central pressure recently measured by the
reconnaissance aircraft was 994 mb (29.35 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Cristobal can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC, and
on the web at www.hurricanes.gov/text/MIATCDAT3.shtml

STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Mouth of the Mississippi River to Ocean Springs MS including Lake
Borgne...3-5 ft
Morgan City LA to Mouth of the Mississippi River...2-4 ft
Ocean Springs MS to Marco Island FL including Mobile Bay, Pensacola
Bay, and Tampa Bay...1-3 ft

The deepest water will occur along the immediate coast in areas of
onshore winds and will likely extend along the coast well to the
east of the center.  Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances.  For information specific to your area, please see
products issued by your local National Weather Service forecast
office.

WIND: Tropical storm conditions are expected within the Tropical
Storm Warning area along the northern Gulf coast today and tonight.

RAINFALL: Cristobal is expected to produce total rainfall
accumulations of 4 to 8 inches across portions of the central Gulf
Coast into the Lower Mississippi Valley, with isolated amounts to
12 inches.  Rainfall totals of 2 to 4 inches with local amounts to
6 inches are expected across portions of the eastern Gulf Coast,
along with the Mid to Upper Mississippi Valley and Northern Plains
near and in advance of Cristobal.  This rainfall may lead to flash
flooding and widespread flooding on smaller streams across portions
of the central Gulf Coast into the Lower Mississippi Valley. New and
renewed significant river flooding is possible along the central
Gulf Coast and into the Mississippi Valley.

TORNADOES: A few tornadoes are possible today and tonight across
eastern Louisiana, southern Mississippi, southern Alabama, and
northern Florida.

SURF:  Swells generated by Cristobal will affect portions of the
northern and eastern Gulf coast during the next couple of days.
These swells are likely to cause life-threatening surf and rip
current conditions.  Please consult products from your local
weather office.
