BEACHNET==> storm frequency less than the one year storm

["wsimmons" <wsimmons@co.monmouth.nj.us>]

hi - i am looking for data just like attached table (copied off the noaa web 
at http://hdsc.nws.noaa.gov/hdsc/pfds/index.html), but instead of beginning 
with one year storms, i am looking for storm frequencies of  less than a 1 
year storm - because most storms during the summer in nj that drive up 
bacteria levels in the ocean and bays near storm drains are <1 year storms -

we have a pay weather site locally that records 6 minute rain levels, and i 
would like to be able to start comparing storm intensity to a storm 
frequency table for storms of less than 1 year frequency,

right now when we compare bacteria levels for these smaller storms we just 
look at the total amount over a 24 hour period, and so the data often comes 
out random - for example, a .5"  drizzle over 12 hours will produce less 
impacts from bacteria-laden storm water than .5" in an hour, because the 
former will have more infiltration and the latter will be more 'flashy' - it 
would be useful when looking at trends for provisional closures/forecasting 
to also have these smaller storms assigned to categories that reflect 
intensity, as noaa is doing for >=1 year storms

if anyone knows where i can start looking for a storm frequency chart for 
storms in the ny/nj metro area of  less than 1 year frequency please let me 
know - or if anyone has crossed this bridge and wants to point me in a 
direction

thanks for your time
