Fire Weather Planning Forecast for PUERTO RICO
National Weather Service SAN JUAN PR
519 AM AST Wed Feb 22 2017

.DISCUSSION...The dominant northerly wind flow will continue to transport
shallow moisture along an old frontal boundary across the region during
the rest of the morning hours. However, a drying trend will follow as
a surface high pressure ridge will build north of the region and winds
become more east to southeast by Thursday and Friday. RH`s across the
southern coastal areas are expected to drop to the mid 40s in some
areas today, but the remainder of the islands minimum RH values should
remain above the critical thresholds. In addition the northerly winds
are forecast to remain just below critical levels. Therefore the risk
of fire danger and spread is low at least for today.
