Hydrologic Outlook
ESFBRO
The Brownsville Texas National Weather Service Office has
implemented Advanced Hydrologic Prediction Service (AHPS) for the
Los Olmos Creek basin in Deep South Texas. AHPS enables the
National Weather Service to provide long-range probabilistic
outlooks. This service is also available on the internet.
In the table below...the 90 through 10 percent columns indicate
the chance the creek could rise above the listed stage levels in
the next 90 days. Example: The Los Olmos Creek near Falfurrias
has a flood stage of 11 feet. There is a 50 percent chance the
Falfurrias forecast point will rise above 1.8 feet during the
next 90 days.
Chance of Exceeding Stages at Specific Locations
Valid [01/07/2026 - 04/07/2026]
Location FS(FT) 90% 80% 70% 60% 50% 40% 30% 20% 10%
-------- ----- --- --- --- --- --- --- --- --- ---
Los Olmos Creek
Falfurrias 11.0 1.6 1.6 1.6 1.6 1.8 2.3 2.6 3.2 5.1
This long-range probabilistic outlook contains numbers that are
calculated using multiple scenarios from 50 years of historical
climatological and stream flow data. These numbers also take
into account current conditions of the creek and soil moisture.
By providing the complete range of probabilistic numbers...the
level of risk associated with the long-range planning decisions
can be determined.
Additional supportive data and explanation are available on the
internet at:
http://water.weather.gov/ahps2/long_range.php?wfo=bro
Long range probabilistic outlooks are issued around the third
Thursday of every month.
