Elsa Grinding Into Cuba, As Florida Waits


MIAMI - Not much has changed in the latest advisory on Tropical Storm Elsa (2 a.m.)

ELSA'S TOP WINDS remain at 65 miles per hour.

THE STORM IS MOVING NW at 15 and is expected to lose some strength as it cuts across Central Cuba.

A tropical storm warning remains posted from Craig Key into the lower Keys, with tropical storm watches for the Upper Keys as well as the west coast of Florida from Flamingo to the Anclote River, and a storm surge warning from Bonita Beach to the Suwannee River.

Breaking down what forecasters are expecting in different regions:

Tropical storm conditions expected in the lower Keys Monday afternoon. Also possible, 1 to 2 feet of coastal flooding, up to six inches of rain.

Parts of south Florida could see flooding from rainfall and isolated tornadoes, anytime between Monday morning and Wednesday morning.

In the Tampa Bay area, a big concern is flooding Tuesday and Wednesday, not just along the coast with storm surge, but also from rainfall and saturated ground, as well as along rivers and creeks.

A Hurricane Warning means that hurricane conditions are expected

somewhere within the warning area, in this case within the next 12

hours. The hurricane conditions are expected to begin shortly after

the first occurrence of tropical-storm-force winds, conditions that

make outside preparations difficult or dangerous. Preparations to

protect life and property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are

expected somewhere within the warning area.

A Hurricane Watch means that hurricane conditions are possible

within the watch area. A watch is typically issued 48 hours

before the anticipated first occurrence of tropical-storm-force

winds, conditions that make outside preparations difficult or

dangerous.

A Storm Surge Watch means there is a possibility of life-

threatening inundation, from rising water moving inland from the

coastline, in the indicated locations during the next 48 hours.

For a depiction of areas at risk, please see the National Weather

Service Storm Surge Watch/Warning Graphic, available at

hurricanes.gov.

A Tropical Storm Watch means that tropical storm conditions are

possible within the watch area.

Interests elsewhere in the Florida peninsula, coastal Georgia and

the Carolinas should monitor the progress of Elsa. Additional

watches and warnings will likely be required later today.

For storm information specific to your area in the United

States, including possible inland watches and warnings, please

monitor products issued by your local National Weather Service

forecast office. For storm information specific to your area

outside of the United States, please monitor products issued by

your national meteorological service.

DISCUSSION AND OUTLOOK

----------------------

At 200 AM EDT (0600 UTC), the center of Tropical Storm Elsa was

located near latitude 20.8 North, longitude 79.6 West. Elsa is

moving toward the northwest near 15 mph (24 km/h), and this general

motion is expected to continue today, followed by a turn toward the

north-northwest on Tuesday. On the forecast track, Elsa is expected

to move across central and western Cuba later today and head toward

the Florida Straits tonight, and pass near the Florida Keys early

Tuesday. Elsa is then forecast to move near or over portions of the

west coast of Florida on Tuesday and Wednesday.

Maximum sustained winds remain near 65 mph (100 km/h) with higher

gusts. Some strengthening is possible before Elsa moves over Cuba

later today, followed by some weakening while the center moves over

land. Slight restrengthening is possible after Elsa moves over the

southeastern Gulf of Mexico.

Tropical-storm-force winds extend outward up to 80 miles (130 km)

from the center.

The estimated minimum central pressure is 1004 mb (29.65 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

www.hurricanes.gov/graphics_at5.shtml?key_messages.

WIND: Hurricane and tropical storm conditions are expected in

portions of central Cuba today. Tropical storm conditions are

expected to begin in the warning area in the Florida Keys by

tonight. Tropical storm conditions are possible in the watch areas

in the Cayman Islands this morning, and in the upper Florida Keys by

tonight. Tropical storm conditions are possible in the watch area

along the west coast of Florida beginning early Tuesday.

STORM SURGE: A storm surge will raise water levels above normal

tide levels by as much as the following amounts in areas of onshore

flow within the hurricane watch and warning areas...

Southern coast of Cuba...3 to 5 ft

The combination of a 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...

Bonita Beach, FL to Suwannee River including Tampa Bay...2 to 4 ft

Flamingo, FL to Bonita Beach, FL...1 to 3 ft

Ocean Reef, FL to Dry Tortugas including Florida Bay...1 to 2 ft

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.

RAINFALL: Across portions of Jamaica, an additional 2 to 4 inches of

rainfall with isolated storm total amounts of 15 inches are expected

through this morning. This rain may lead to scattered flash

flooding and mudslides, some of which could be significant.

Across portions of Cuba today, rainfall of 5 to 10 inches with

isolated maximum amounts of 15 inches is expected. This will result

in significant flash flooding and mudslides.

Across the Cayman Islands today, rainfall of 3 to 5 inches is

expected. This rain may lead to scattered flash flooding.

Rainfall from Elsa will impact portions of the Florida Keys, Florida

Peninsula and the coastal Southeast this week. Amounts of 2 to 4

inches with localized maximum amounts up to 6 inches will be

possible across Florida and Coastal Georgia today through

Wednesday, which may result in isolated flash, urban, and minor

river flooding. Coastal portions of South Carolina are expected to

receive 1 to 3 inches of rain, with local amounts to 5 inches

Wednesday into Thursday, which could lead to isolated flash

flooding.

TORNADOES: A couple of tornadoes are possible across southern

Florida this afternoon into Tuesday.

SURF: Swells generated by Elsa will spread westward along the

southern coast of Cuba today. Swells will increase near the

Florida Keys and south Florida later today and spread northward

along the west coast of Florida tonight and Tuesday. Please

consult products from your local weather office for more details.
