Hydrologic Outlook issued April 29 at 11:35AM AST by NWS San Juan PR
ESFSJU Increasing moisture and instability from a nearby trough will maintain the potential for heavy showers and thunderstorms through the end of the workweek. Since rains have been abundant in the last couple of days in Puerto Rico, soils are saturated and rivers are running high. Therefore, there is an elevated to significant threat of flooding for most of the area. Showers will again develop today, but the activity is expected to be even more widespread on Wednesday and Thursday. Additionally, winds are light, so any rain that develops will be long-lasting. The areas of highest risk are the interior

ESFSJU Abundant moisture, along with a series of troughs, will continue to enhance the potential for showers and thunderstorms today, and stretching into at least Thursday. At this time, USGS river sensors indicate that most streams are running normal to much above normal, and soils are saturated along eastern, interior and western Puerto Rico. Some rivers reached action to minor flood stage with yesterday's heavy rains. Additionally, winds are expected to be weak through much of this period, so any rainfall activity that develops will be long-lasting. In general, we are expecting additional rainfall accumulation of 2 to 4 inches

ESFBYZ The latest snow data from the NRCS and NOHRSC shows a significant snowpack existing between 5500 and 7500 feet. In this elevation 3 to 7 inches of water is contained within the snowpack. A storm system is expected to impact the area from Sunday afternoon through Monday. From Sunday afternoon into early Monday morning temperatures will be warm enough for rain to fall in this mid elevation layer over the Beartooth, Absaroka and Crazy mountains and foothills. The Pryor and Bighorn mountains and foothills will see rain potential from late Sunday evening into early afternoon Monday. A few thunderstorms

ESFSJU Showers and thunderstorms have increased in frequency in the past couple of days, mostly in the afternoon hours for portions of the east, west, north and interior of Puerto Rico. This pattern will continue through much of the workweek, as a series of frontal boundaries and troughs continue to reach the islands. In general, these same areas should see the bulk of the rainfall activity each day of the workweek, but showers will also stream occasionally across portions of the Virgin Islands and the San Juan metro area as well. So far, there is a small rainfall deficit along

ESFLKN Near record warmth is expected in portions of Northern and Central Nevada thru the end of the week. This will accelerate snowmelt and enhance runoff into area creeks and rivers. Creeks and rivers that are susceptible to rapid water level rises will be most impacted. Waterways affected include, but are not limited to Martin Creek in Humboldt County, the Owyhee River in Elko County, the Bruneau River in Elko County, the Jarbidge River in Elko County, and Salmon Falls Creek in Elko County. The latest official forecast no longer indicates that Salmon Falls Creek will move into action stage
