DROUGHT INFORMATION STATEMENT
NATIONAL WEATHER SERVICE SAN JUAN PR
348 PM AST Sat Mar 25 2017

...D0 was reduced over northern Puerto Rico...Abnormally dry conditions
are still observed across the southern-most portions of the island...

...The dryness observed across these areas is not classified as
drought by the U.S. Drought Monitor...

SYNOPSIS...

There are 90-day rainfall deficits across some areas in eastern
interior and southern Puerto Rico. Soil moisture data is also
consistent with the 90-day rainfall pattern. The drier soils are
noted across the southern areas of Puerto Rico. The streamflows
are generally in the normal to above normal range, however, there
are a few outliers across eastern interior and southern Puerto
Rico. These outliers are running below the 24th percentile, which
is below to well-below normal. Most of the representative wells
across southern Puerto Rico are indicating a downward trend.

RIVER AND STREAM FLOW CONDITIONS.
The 28-day average streamflow from the USGS river gauge network
indicates most of the streamflows across Puerto Rico running above
the 25th percentile, which is in the normal to above normal
range. There are a few outliers across eastern interior and
southern Puerto Rico running below to well-below the normal range.


CLIMATE SUMMARY...
A wetter pattern has been observed across the forecast area the
last few days. Rainfall accumulations alleviated the dryness,
particularly across the northeast portion of the island. As a
result D0 was reduced across northeast Puerto Rico.

PRECIPITATION/TEMPERATURE OUTLOOK...
NEXT 7 DAYS.
There is a better chance for rainfall activity as trofiness aloft
will prevail through early next week. This will grant instability
and enough moisture across the local islands. A drier weather
pattern is expected by mid week, with limited activity through the
end of the period.

EXTENDED FORECAST.
Typically, the dry season continues across the local islands
through the end of March with a transition during April and the
onset of the wet season in May. ENSO conditions are currently
neutral with no impact on the Caribbean rainfall. Warm Sea Surface
Temperatures(SSTs) in the northwest Caribbean may lead to above
average humidity and atmosphere instability going out of the dry
season, which tilts the odds toward a wetter first half of the wet
season. With SSTs remaining above average through the period, air
temperature, especially at night are also expected to be warmer
than average. There are increasing chances for El Nino
development into the fall, which may result in a drier pattern
across the local islands by then.
