DISCUSSION AND OUTLOOK
At 200 PM AST (1800 UTC), the center of Hurricane Elsa was located
near latitude 13.7 North, longitude 62.5 West. Elsa is moving toward
the west-northwest near 29 mph (46 km/h), and this motion is
expected to continue during the next couple of days, with some
decrease in forward speed expected Sunday night. On the forecast
track, Elsa will move away from the Windward Islands during the next
several hours, move across the eastern Caribbean Sea this afternoon
and tonight, and move near the southern coast of Hispaniola late
Saturday or Saturday night. By Sunday, Elsa is forecast to move
near Jamaica and portions of eastern Cuba, and move near portions of
central and western Cuba Sunday night and early Monday.
Reports from a NOAA Hurricane Hunter aircraft indicate that
maximum sustained winds are now near 85 mph (140 km/h) with higher
gusts. Little change in strength is forecast during the next
48 hours. Some decrease in winds is possible on Monday as Elsa
interacts with Cuba.
Hurricane-force winds extend outward up to 25 miles (35 km) from
the center and tropical-storm-force winds extend outward up to
140 miles (220 km).
The minimum central pressure estimated from the NOAA Hurricane
Hunter data is 991 mb (29.26 inches).
HAZARDS AFFECTING LAND
Key messages for Elsa can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5, WMO header WTNT45 KNHC and
on the web at
WIND: Tropical storm conditions are expected in the tropical storm
warning area in the Windward Islands for the next few hours.
Tropical storm conditions are expected in portions of the Windward
and southern Leeward Islands within the tropical storm warning areas
and are possible in the tropical storm watch areas later today.
Hurricane conditions are expected in the hurricane warning area in
Haiti by late Saturday and are possible in the hurricane watch area
in the Dominican Republic by late Saturday. Hurricane conditions
are possible on Jamaica late Saturday or Sunday.
STORM SURGE: A storm surge will raise water levels by as much as 1
to 3 feet above normal tide levels in areas of onshore winds in the
hurricane warning area in the Windward Islands and 2 to 4 feet
above normal tide levels along the southern coast of Hispaniola.
RAINFALL: Elsa is expected to produce rainfall totals of 4 to 8
inches with maximum amounts of 15 inches today across the Windward
and southern Leeward Islands, including Barbados. This rain may lead
to isolated flash flooding and mudslides.
Over Puerto Rico, rainfall of 1 to 3 inches with localized amounts
of 5 inches is expected late today into Saturday. This rain may lead
to isolated flash flooding and minor river flooding, along with the
potential for mudslides.
Across portions of southern Hispaniola and Jamaica, rainfall of 4 to
8 inches with isolated maximum amounts of 15 inches is possible
Saturday into Sunday. This rain may lead to scattered flash
flooding and mudslides.
SURF: Swells generated by Elsa will spread westward across the
Caribbean Sea during 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.
