Alright here we go mother nature round two:
Latest Sandy Forecast:
- The centre of hurricane Sandy is about 180 km SE of Atlantic City and 285 km SSE of NYC. Sandy still a cat 1 hurricane with sustained winds of 150 km/h moving NW at 44 km/h
- Sandy is moving more quickly now towards southern New Jersey so landfall is expected early this evening **within the next few hours** On the forecast track the storm is expected to make landfall along or just south of the southern NJ coast by early evening local time
- Sandy will begin to transition into a frontal or wintertime low later today or tonight, but right now is still gaining its strength from the warm waters. Little change in strength is expected before landfall though
- This is the largest storm in Atlantic history with a gale diameter of 1513 km...Sustained tropical storm force winds are already occurring from North Carolina to southern New England right now. As winds increase...winds affecting upper levels of high-rises will be even stringer than ground level later today
- The reach and impact of this storm is truly massive: 4 m waves are occurring across an incredible 2500 km diameter. Record storm surge flooding has already occurred in regions along the New Jersey coast this morning, and the highest water levels recorded in over a century of record keeping are expected over much of the New Jersey and New York coasts this evening during the 8 - 9 pm EDT high tide cycle.

- The combination of an extremely dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters...
- Flooding rains of over 400 mm may fall in some coastal regions and 100+cm of snow may fall in the mountains of west Viginia today through Wednesday
- The Canadian Hurricane Centre is issuing updates every 6 hours for Ontario, Quebec & the Maritimes
- As Sandy undergoes extra-tropical transition as it heads toward the New Jersey coast rain directly related to post-tropical Sandy will begin to affect Southern Ontario later this afternoon **first bands moving through GTA right now** with the heaviest bands reaching the province this evening and overnight into Tuesday.
- A general 20 to 40 mm are possible with locally higher amounts in excess of 50 mm possible. Rainfall amounts could vary greatly with location depending on the movement of some of the smaller heavier rainbands with this system.
- The precipitation could mix with or change to snow over parts of Ontario and extreme Western Quebec as temperatures approach the
freezing mark north and west of the storm.
- Rain is not expected to reach the southwestern Maritimes until Tuesday morning but could persist into Wednesday from a developing
frontal system not directly associated with Sandy. Amounts could be significant and total amounts could exceed 50 millimetres through Wednesday.
- Wind warnings have been issued for parts of the St Lawrence River Valley beginning later today and wind warnings are also in place for all of Southern Ontario (incl Toronto & Montreal) for >90 km/h wind gusts beginning later tonight and continuing on Tuesday.
- These wind gusts have the potential to cause broken tree limbs or in some cases uprooted trees which may result in downed utility lines.
- Gusty winds can also be expected in the Maritimes starting Monday afternoon and persisting Tuesday.
- Large waves are very likely over portions of the Great Lakes beginning later today and into Tuesday. High seastates up to 7 metres
are possible over Southern Lake Huron and higher than normal water levels are expected on the St Lawrence River during high tide this evening and especially Tuesday evening that could result in coastal flooding in the Quebec City region.
- Meanwhile back at the ranch...rain ending near noon today and then risk of showers
- Mild and wet weather will continue through midweek under moist southwest flow. Halloween night looking soggy at this point but I will take a closer look at timing later today
- Drier and slightly cooler weather will build back in late this week
