A very useful tool produced by MetStorm™ is the total storm map. This map uses the latest and greatest data from Weather Decision Technologies POLARIS quantitative precipitation estimates (PQPE), real-time and ghcn daily precipitation gauges, and satellite data from NOAA STAR’s Hydro-estimator. It seamlessly blends together these three sources to create a cohesive product which is an ideal solution for viewing precipitation.

In today’s post we will give an example of MetStorm’s™ total storm map product using a storm that occurred in Crescent City, California on March 22-25 2015. 

This storm was a result of a weak atmospheric river leading to a series of pacific low pressure systems moving through the area, supplying significant moisture and lift for the storms, as seen below in the US surface analysis and satellite composite maps.

The Eureka National Weather Service office posted a station list detailing the 72-hour storm total precipitation for various stations in the area. This list of stations can be found here. The highest recorded precipitation according to this page was 4.40″ in Gasquet Ranger Station with a close second of 4.13″ at Camp Six Raws Near Gasquet.

One of the many advantages of MetStorm™ is its ability to interpolate between stations using the PQPE and satellite data, allowing for additional rainfall amounts to be estimated. This is especially beneficial for areas in complex terrain. For the Crescent City, California case, MetStorm™ estimated up to 6″ of rainfall over the area for the 72 hour period (shown below). This area of the country is fairly mountainous, and it is fair to assume that there are not enough rain gauges to sample various elevations; so it’s realistic that MetStorm™ estimated higher amounts of rainfall for this area.


The applications for this map can be for media inquiries, situational awareness, and emergency management; just to name a few. The integration of the high quality data sources is key in its success at analyzing precipitation in a variety of situations, whether it be in the mountains, plains, or anywhere in between MetStorm™ can handle it all.
