Drains in Fall Creek are working like champs as always, but my street is getting flooded right now. Never seen it like this. Not a good sign for the areas around us.

New NHC forecast has Harvey dipping offshore again. Our forecast puts it a little further offshore than theirs which might give it time to reintensify.

From NWS Houston:


This is a FLASH FLOOD EMERGENCY from the Bay City area to Wharton to
Waller across the Houston Metro area to Stafford to Friendswood to
League City and Santa Fe. Travel across the area is severely hampered
if not impossible. Over 1000 high water rescues have been performed
and in some places emergency crews cannot reach the worst hit areas.
5 fatalities have been reported.
Some people are using attics and
the second floor to escape the rising flood waters.

Area Forecast Discussion
National Weather Service Houston/Galveston TX
601 AM CDT Sun Aug 27 2017

...FLASH FLOOD EMERGENCY FOR LIFE-THREATENING CATASTROPHIC FLOODING...

.DISCUSSION...
Epic and catastrophic flooding has occurred in and around the
Houston and Galveston areas and surrounding communities overnight,
and very heavy rains continue falling across these areas early
this morning. Rainfall totals between Saturday evening and early
this morning have totaled 15 to 30 inches.
Tropical Storm Harvey
is approximately 50 miles east southeast of San Antonio and has
remained nearly stationary all night long. Showers and thunderstorms
along Harvey's feeder bands have spread 4 to 6 inch per hour producing
rainfall rates resulting in this historic event. Activity continues
spreading across already devastated areas with hourly rainfall
rates averaging around 4 to 5 inches in the Matagorda-Brazoria
County storms and around 6 to 7 inches in the Galveston-Harris
County area storms. We might get a break from the rain some time
later today, but additional storm development is likely overnight.
It is possible that these new storms could become concentrated a
little further westward than this morning's activity. However,
with Harvey expected to remain in the same general area between
its current location and the coast over the next several days,
additional life-threatening rainfall totals of 15 to 25 inches
with isolated higher amounts are possible across the Flash Flood
Watch area over the next several days, and results could be
devastating if any of these rains fall where catastrophic flooding
has already occurred

Bay,

How much of an east shift has taken place in the forecast? I'm in Lake Charles and we are literally on the edge of this. All it takes would be a small shift east and we will be having issues here.
