WIND: Tropical storm conditions are expected within the warning area
during the next few hours.

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...
=20
Matagorda, TX to the Mouth of the Mississippi River, LA...1-3 ft
=20
The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves. 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.

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at1.shtml?peakSurge.
=20
SURF: Swells generated by Arthur are likely to cause
life-threatening surf and rip current conditions along the
northwestern Gulf Coast for the next day or two. Please consult
products from your local weather office.
