Each page within a spreadsheet shows period-of-record rainfall totals in inches (based on area-weighted average values) for 1915 through the previous calendar year by month, wet season, dry season, calendar year, or water year. Summaries are tabulated by specific geographic areas, such as county or drainage basin boundaries, for that portion of the geographic area within SWFWMD boundaries.

We're still 14 inches shy of that extremely crude estimate, but it's also not over yet. Or do they? Using the Kraft rule, and Harvey's motion since landfall (150 miles in 84 hours = 1.6 kt), you would get a maximum of 64.4 inches. David Roth (NOAA/WPC) created a chart using storms from 1991-2005 and found that the average landfalling storm produced 13.3 inches of rain.īut when a storm does not keep moving, these climatology-based estimates break down. So for Harvey which was moving at 6 kts (7 mph) when it made landfall, you would get a maximum of 16.7 inches (if it kept moving at that speed). Kraft introduced a rough guideline for maximum rainfall totals from a landfalling tropical cyclone: divide 100 by the forward speed of the storm in knots. People have calculated bulk averages for "typical" rainfall amounts from landfalling storms. Typically, storms make landfall and keep moving. Later today, it will have spent more time as a tropical storm or higher after landfall than it did prior to landfall. If you add up all of the time it was a named storm prior to landfall (including the eastern Caribbean part) you get 90 hours. It has also been a tropical storm or hurricane for 84 hours AFTER making landfall. The center is now just 150 miles from where it made landfall on Friday night. The primary reason for these incredible amounts is that Harvey has barely moved. A huge area is blanketed (or submerged in this case) by totals of 1 foot or greater. The accumulation map looks more like inches of snow after a strong Nor'easter, not inches of rain in a few days. Storm-total rainfall maps for Amelia 1978, Easy 1950, and Claudette 1979. The report of 49.2" became the all-time record holder for highest rainfall amount associated with a landfalling tropical cyclone in the continental United States. As of late Tuesday morning, several stations are referenced in a NWS list that are now at over three feet of rain: This site provides current rainfall totals for Ventura County and nearby counties. (SERCC)Īs we enter Day 5 of heavy rain in Texas, the totals are staggering and still accumulating. Rainfall totals from Friday morning through Tuesday morning.
