HANNA Land Hazards

• RAINFALL - Hanna is expected to produce the following rain accumulations and flood threats through Monday:
• SURF - Swells generated by Hanna will continue to affect much of the Texas and northeastern Mexico coasts through early Monday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
• TORNADOES - Isolated tornadoes are possible through this evening across parts of south Texas

DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Depression Hanna
was located near latitude 25.6 North, longitude 100.6 West. The
depression is moving toward the west-southwest near 9 mph (15 km/h),
and this motion is expected to continue through Monday. On the 
forecast track, the center of Hanna should continue to move farther 
inland over northeastern Mexico.
  
Maximum sustained winds have decreased to near 35 mph (55 km/h) 
with higher gusts. Additional weakening is expected as the center
of Hanna moves farther inland.  Hanna is expected to become a 
remnant low on Monday and dissipate by Monday night.
 
The estimated minimum central pressure is 1002 mb (29.59 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Hanna 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.
 
RAINFALL:  Hanna is expected to produce the following rain 
accumulations and flood threats through Monday:

South Texas...Additional 2 to 5 inches.  Storm total amounts 6 to 12 
inches, isolated 16 inches. 
Northern Mexican states of Coahuila, Nuevo Leon, Tamaulipas...6 to 
12 inches, isolated 16 inches. 
Northern Mexican states of northern Zacatecas, northern San Luis 
Potosi, and eastern Durango...1 to 4 inches.

This rain will produce life-threatening flash flooding, rapid rises 
on small streams, and isolated minor river flooding in South Texas. 
Flash flooding and mudslides are likely across Northern Mexican 
states.
 
SURF:  Swells generated by Hanna will continue to affect much
of the Texas and northeastern Mexico coasts through early Monday.
These swells are likely to cause life-threatening surf and rip
current conditions.  Please consult products from your local weather
office.
 
TORNADOES:  Isolated tornadoes are possible through this evening 
across parts of south Texas

Tropical Depression Hanna Discussion Number  16
NWS National Hurricane Center Miami FL       AL082020
400 PM CDT Sun Jul 26 2020
 
Surface observations along with radar and satellite imagery show
that Hanna continues to weaken as it moves farther inland.  There
have been no recent observations of sustained tropical-storm-force
winds, and Doppler velocities have continued to decrease.  Based on
these trends, the initial wind speed has been reduced to 30 kt.
Hanna should continue to spin down while it moves over the high
terrain of northeastern Mexico.  The system is forecast to become
a remnant low in 12-18 hours, and should dissipate over the 
mountains of Mexico by late Monday, if not sooner.
 
Hanna is moving west-southwestward or 245/8 kt. The cyclone should 
continue on this general heading and speed until dissipation
occurs.  The updated NHC track forecast is again similar to the
previous advisory and is close to the dynamical model consensus.

This is the last NHC advisory on Hanna.  Future information on this 
system can be found in Public Advisories issued by the Weather 
Prediction Center beginning at 10 PM CDT, under AWIPS header 
TCPAT3, WMO header WTNT33 KWNH, and on the web at 
http://www.wpc.ncep.noaa.gov. 
 
Key Messages
 
1. Heavy rainfall from Hanna has already produced numerous reports 
of flash flooding across south Texas.  Additional heavy rainfall 
will continue to result in life-threatening flash flooding over 
south Texas and northern Mexico, and isolated minor river flooding 
in south Texas.
