Govt got two good years of rainy season and now 2017 seems to be a test of state of readiness.
The first hit was upwards of $25mill, one wonders what is on the horizon.
The elements have set us up for high flooding risks.

[bluefete]

Even though there is not a direct threat, feeder bands could still affect us.

Traffic is a mess outside there in ALL directions. Thank God schools are closed.

MET Office Bulletin #3

INCLEMENT WEATHER OVER THE NEXT 24 HOURS DESPITE WEAKENING OF TROPICAL STORM
DON

At 2:00 p.m. today Tuesday 18th July, 2017, the centre of Tropical Storm Don
was located near 11.5N Latitude and 58.7W Longitude or approximately 200 km
east of Tobago.

Don has weakened over the last 3 hours and is now a marginal Tropical Storm.
Maximum sustained winds are near 65km/hr. The system is currently moving
toward the west near 31 km/hr and this general motion is expected to
continue through Wednesday. On the forecast track, the centre of Don will
move across the Windward Islands, north of Tobago, later tonight. The
Trinidad and Tobago Meteorological Service (TTMS) continues to monitor any
changes in the forecast track.

The leading edge of Don is already affecting Tobago with light rain/showers.
An increase in activity including thundershowers and gusty winds, at times
in excess of 60 km/hr, is forecast to affect Tobago overnight. Rainfall
experienced over Trinidad today was not associated with Tropical Storm Don
but rather local dynamics due to intense daytime heating and light low level
winds. As the afternoon progresses Tropical Storm Don will bring additional
periods of showers and/or rain and a few thundershowers over Trinidad. Gusty
winds, street and flash flooding can accompany heavy showers and
thundershowers.

Don is expected to produce rainfall accumulations of 40-60 mm with heavier
amounts possible in some areas. The possibility of landslides/landslips
exists. Sea conditions can also become choppy in the vicinity of heavy
showers and thundershowers.

All interests in Trinidad and Tobago, Grenada and its Dependencies are asked
to monitor the progress of this system and pay close attention to
information being issued by the TTMS by visiting our website at
http://www.metoffice.gov.tt, downloading our mobile app (search: TT Met Office) and
following us on Twitter and Facebook. The TTMS is reminding citizens that we
are in the Hurricane Season and adequate preparation is advised.

WE WISH TO UNDERSCORE THAT AT THIS TIME TRINIDAD AND TOBAGO IS NOT UNDER ANY
TROPICAL CYCLONE WATCH OR WARNING.

[redmanjp]

i guess the met office didn't bother issuing a watch/warning for us because of the small storm force wind field

[toyolink]

Well if thus far this isn't a leading edge of Don and we already soaked, when the system does arrive tonite , it had better be low on saturation capacity.
Right now 'we already wet and ready'.

It is a good thing that the rains did not come from Don.

Have you tuners seen the amount of flash flooding COUNTYWIDE, today?

[redmanjp]

^ but river levels would now be high due to those rains which would then cause a high likelihood of flooding tonight when Don's rain bands do affect us.

[pugboy]

when is high tide ?

[redmanjp]

high tide is 11:32pm - so if rain falling around dat time is trouble!

[cornfused]

Not sure when is high tide, but a video on looptt showed flooding in Claxton Bay, Penal, Maraval, Diego Highway, City Gate, La Brea, Rousillac, Endeavour, M1 Ring Road, San Juan and Mt. Lambert among other areas

[shake d livin wake d dead]

In other words...if we get good rain tonight...more flood in we mc

[SRASC]

[pugboy]

That is worst possible time as all the runoff from this afternoon still making its way down watercourses etc
Really a problem for the low lying areas though

high tide is 11:32pm - so if rain falling around dat time is trouble!

(0300 UTC), the remnants of Don were located near latitude 11.9
North, longitude 62.5 West. The remnants are moving quickly toward
the west near 25 mph (41 km/h), and this motion is expected to
continue during the next couple of days.

The aircraft data indicate that maximum sustained winds are near 40
mph (65 km/h) with higher gusts. These winds are occurring over
the waters of the far southeastern Caribbean Sea.

Tropical-storm-force winds extend outward up to 45 miles (75 km)
to the north of the center.

The estimated minimum central pressure is 1012 mb (29.89 inches).


HAZARDS AFFECTING LAND

WIND: Gusts to tropical storm force in squalls are still possible
across the Windward Islands overnight.

RAINFALL: The remnants of Don are expected to produce total rain
accumulations of 3 to 6 inches, with isolated higher amounts, across
Trinidad and Tobago, the southern Windward Islands, and northeastern
Venezuela through Wednesday. These rains could produce
life-threatening flash floods and mudslides, especially in
mountainous areas.
