Yes we had that during Ida

ouch !

I have a friend in the Plainfield area and in one of the recent flooding events there it came pouring in the ground level basement window wells. Could be any number of reasons with those excessive rates. Pumps or drains with those rates are not a lock that you are safe.

2026 Mid-Atlantic Severe Storm General Discussion
midatlanticweather replied to Kmlwx's topic in Mid Atlantic
Mesoscale Discussion 1691 NWS Storm Prediction Center Norman OK 1253 PM CDT Tue Jul 21 2026 Areas affected...portions of the Mid-Atlantic Concerning...Severe potential...Watch likely Valid 211753Z - 211930Z Probability of Watch Issuance...80 percent SUMMARY...Multiple rounds of numerous, strong to severe thunderstorms will bring a risk for primarily damaging wind gusts to portions of the Mid-Atlantic through this evening, with a couple of brief tornadoes and isolated large hail also possible. DISCUSSION...Scattered thunderstorms have developed along the Blue Ridge as of 1750 UTC ahead of a mid-level shortwave trough that is progressing eastward across the upper Ohio Valley. Expectation is for this activity to spread eastward this afternoon with additional thunderstorms likely to progress into the region from the northwest this evening. Filtered heating of the downstream environment has resulted in temperatures warming into the upper 80s/near 90 F. With dewpoints in the low/mid 70s, this is supporting moderately strong buoyancy across the region. While effective shear of 35-45+ kts will favor storm organization, widespread thunderstorm development and cold pool consolidation are anticipated to yield a multicellular/outflow-dominant storm mode, with damaging to severe wind gusts the primary risk. A couple of brief tornadoes and isolated large hail will also be possible. Additionally, guidance suggests that air mass recovery will occur in the wake of these initial storms, which may allow the severe threat to persist into this evening as additional convection progresses southeastward into the region. Given this severe potential, watch issuance will likely be needed in the next hour or two. ..Chalmers/Mosier.. 07/21/2026 ...Please see www.spc.noaa.gov for graphic product...

Central PA Summer 2026 Discussion/Obs Thread
Elim72 replied to Voyager's topic in Upstate New York/Pennsylvania
It seems like the worst is setting up in Southern PA any thoughts? -
could have also been coming in through under a door or they just had the sump pump without the drains along the walls
-
Contender for stupidest post of the thread… you’re better than that - six inches in 90 minutes.
-
Quite possible with those rates they could not keep up. Rainfall of 5-6" in 90 minutes is EXTREME.
-
we had the same type of event last July 14 in central/north Jersey my sump pump was going off every few seconds
-
If you could have seen it come down it would overwhelm almost anything...never seen rain that heavy in that short of a period here. In the NE thread they posted a graphic-a once in 200 yr event
-
those folks ever hear about french drains and sump pumps ?
-
Already a confirmed tornado in northeast PA. Several warnings up towards NY. Dynamics FTW.

Central PA Summer 2026 Discussion/Obs Thread
Itstrainingtime replied to Voyager's topic in Upstate New York/Pennsylvania
Discreet cells have fired quickly over the past 20 minutes in York and Lancaster counties. Exactly where there has been some clearing over the past copule of hours. -
yes numerous basements flooded and it's still going-gauge has over 5 inches of rain in about 90 min
-
My area as well. Taking dead aim. Thankfully they are moving quickly along so any intense rainfall rates should not last that long with these isolated pop ups. Torrential downpours still likely.
-
Sparta about to get hit again - sky is so dark here but everything just to the north.
-
After heading a little more north than projected, recon finds a slight SW jog.
