.DISCUSSION...
A thick upper-level cloud deck will continue to move over the
region. This will delay the onset of afternoon showers, that are
expected to develop mainly to the north and west of Lajas.
Temperatures should remain in the mid 80s, but higher moisture
content today will lead to RH`s in the mid and upper 60s, which
will result in heat indices ranging from 98F to 103F. Light
easterly winds expected early this morning but the sea breeze will
increase wind speeds up to 16 mph with gusts near 30 mph from the
southeast.
Una densa capa de nubes altas continuara sobre la region. Esto
atrasara el desarrollo de aguaceros en la tarde, que se esperan
mayormente en los municipios al norte y oeste de Lajas. Las
temperaturas deben permanecer en los medios 80 grados, pero un
aumento en la humedad hoy resultara en valores de humedad relativa
entre los medios a altos 60. Lo cual causara indices de calor
entre 98F a 103F grados. Se esperan vientos leves esta manana,
pero la brisa marina del sureste aumentara los vientos hasta 16
mph con rafagas cerca de las 30 mph.
