Tropical Storm Amanda Discussion Number   4
NWS National Hurricane Center Miami FL       EP022020
1000 AM CDT Sun May 31 2020
 
Visible satellite imagery and surface observations show that the
center of Amanda has moved inland over southeastern Guatemala.  The
system is producing a large area of deep convection and heavy
rainfall over much of southern Guatemala, El Salvador, and western
Honduras. Although the center is inland, recent reports from El
Salvador indicate some areas are receiving winds gusts above
tropical storm force. The initial intensity will remain 35 kt for
this advisory, but rapid weakening should begin very soon as the
center moves farther inland. The system is likely to degenerate
into a remnant low pressure area or dissipate over the the
mountainous terrain of Guatemala later today or tonight.
 
Amanda is moving north-northeast or 015/8 kt. The cyclone is 
embedded within a larger cyclone gyre located over eastern Mexico, 
and Amanda or its remnants should turn northward today, and then 
northwestward tonight and Monday as it steered around the gyre. 
Amanda's remnants should move over eastern Mexico on Monday and be 
near the southern Bay of Campeche by late Monday and Tuesday, which 
could allow for the formation of a new tropical cyclone.  Although 
the official forecast implies a continuous track of the system, it 
is certainly possible that the low-level center will dissipate and 
that a new low will form in association with Amanda's remnants over 
eastern Mexico or the southern Bay of Campeche.  Please refer to 
NHC's Atlantic basin Special Tropical Weather Outlooks for more 
details on possible tropical cyclone development in the southwestern 
Gulf of Mexico.
 
The main hazard from Amanda, and the larger gyre in which the 
cyclone is embedded, is expected to be heavy rainfall. These rains 
could cause life-threatening flash floods and mudslides across 
portions of Central America and southern Mexico, and these threats 
will continue over the next several days even after Amanda is no 
longer a tropical cyclone.  For additional information, see products 
issued by your national meteorological service.
