Tropical Weather Discussion for North America, Central America
Gulf of Mexico, Caribbean Sea, northern sections of South
America, and Atlantic Ocean to the African coast from the
Equator to 32N. The following information is based on satellite
imagery, weather observations, radar and meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through
1030 UTC.

...SPECIAL FEATURES...

Tropical Depression ETA continues to produce heavy rains and
life-threatening flooding to sections of Central America. The
center of Tropical Depression ETA, at 05/0900 UTC, is inland
over Honduras near 14.5N 87.0W. ETA is moving toward the WNW, or
300 degrees, at 7 kt. The estimated minimum central pressure is
1006 mb. The maximum sustained winds are 25 kt with gusts to 35
kt. Precipitation: scattered to numerous strong is from 150 nm
to 360 nm from the center in the E semicircle, in the coastal
waters from Honduras to Costa Rica; and from 150 nm to 250 nm
from the center in the NW quadrant in Honduras, Belize, and
Guatemala. Scattered moderate to isolate/widely scattered strong
is within 180 nm of SW Cuba. Other isolated moderate to locally
strong is elsewhere, from Hispaniola westward, including in
Central America. Please, read the latest NHC Public Advisory at:
https://www.nhc.noaa.gov/text/MIATCPAT4.shtml, and the Forecast
Advisory at https://www.nhc.noaa.gov/text/MIATCMAT4.shtml, for
more details. Rainfall may cause catastrophic, life-threatening
flash flooding and river flooding, along with landslides in
areas of higher terrain of Central America. Flash flooding and
river flooding are possible in Nicaragua, Honduras, Guatemala,
Belize, Panama, Costa Rica, El Salvador, and southeastern Mexico.

...TROPICAL WAVES...

An Atlantic Ocean tropical wave is along 41W/42W from 16N
southward, moving westward at 10 to 15 kt. Precipitation:
Isolated showers are noted from 09N to 10N between 41W and 43W.

An Atlantic Ocean tropical wave is along 57W, from 15N
southward, moving westward at 10 to 15 kt. Precipitation:
Scattered moderate to strong is from 02N to 09N between 50W and
58W.

...MONSOON TROUGH/ITCZ...

The monsoon trough passes through the coastal plains of Senegal
near 15N17W to 10N20W to 06N27W. The ITCZ continues from 06N27W
to 05N40W to 05N50W. Precipitation: Scattered moderate isolated
strong is from 03N to 11N between 10W and 35W, and from 12N
southward between 44W and 59W.

GULF OF MEXICO...

Broad surface anticyclonic wind flow covers the Gulf of Mexico.
A surface ridge passes through Louisiana, to 22N98W in coastal
Mexico. Rain showers are possible, to the south of the line that
runs from the Florida Keys, to 23N90W in the south central Gulf
of Mexico, to the coast of Mexico along 20N97W. Precipitation
that may occur east of 90W is related to Tropical Depression ETA.

Strong high pressure, extending into the region from the western
Atlantic Ocean, will maintain fresh to strong NE winds in the
southeastern half of the basin, through early Friday. The wind
speeds will remain fresh to strong in the eastern Gulf of Mexico
during the upcoming weekend. The remnant low of Tropical
Depression ETA will re-intensify into a tropical cyclone on
Friday night in the NW Caribbean Sea. Tropical storm conditions
are possible in the Florida Straits on Sunday and Monday.

CARIBBEAN SEA...

Tropical Depression ETA continues to produce heavy rains and
life-threatening flooding to sections of Central America. The
