Tropical Cyclone Information Statements


2:45 AM ADT Thursday 28 August 2014
Tropical cyclone information statement for:

NEWFOUNDLAND

For hurricane Cristobal.

The next statement will be issued by 9:00 AM ADT.

Cristobal (crees-toh-bahl) heading for the Grand Banks - to merge with non-tropical low pressure and front.

1. Summary of basic information at 3.00 AM ADT.

Location: 35.2 north 69.3 west.

About 570 kilometres east of Cape Hatteras.

Maximum sustained winds: 120 km/hour.

Present movement: northeast near 30 km/h.

Minimum central pressure: 983 MB.

2. Public weather impacts and warnings summary.

Rainfall - with areas of heavier rainfall due to a combination of Cristobal and non-tropical weather features north of the hurricane. Details below.

Summary of the weather setup: as hurricane Cristobal races northeastward toward the Grand Banks, a cold front will move slowly southward across Atlantic Canada during the day today. The speed of the front will be slowed as Cristobal approaches, so there may be locally heavy rainfall accumulations as a result. By Friday morning the two systems will merge into one giant area of low pressure with rain and gusty winds extending back into the Maritimes. The airmass in the wake of this system will be distinctively fall-like.

A. Wind.

Winds will become increasingly gusty out of the north across Atlantic Canada overnight tonight into Friday. These winds will not technically be related to Cristobal but will be part of the combined area of low pressure. These winds are still not expected to reach warning criteria. Newfoundland could see gusts in the 50 to 80 km/h range.

B. Rainfall.

Rainfall is not expected to be directly related to Cristobal and will be highly variable across Atlantic Canada. Some areas could see 50 millimetres or more due to the slow motion of the front and embedded downpours. Some models indicate a possibility of 75 millimetres but pinpointing the location of that possibility will be very difficult. We may have a better idea by Thursday morning. Once again - the rainfall will be indirectly related to the hurricane.

C. Surge/waves.

Atlantic coastal Nova Scotia will see ocean swells giving moderate surf and rip tide conditions this afternoon, tonight and Friday morning. The same situation is expected for Newfoundland's southern coastlines on Friday.

3. Marine weather impacts and warnings summary.

The main concerns with this storm - and its interaction with the non-tropical weather features - are very large waves and hurricane force winds that are forecast over the Southern Grand Banks.

Interests in the Northern Grand Banks should remain on alert in case there are indications of a farther-north track. The hurricane will be gaining energy as a post-tropical storm and will likely possess high westerly to northwesterly winds immediate to the left (north) of its track as the centre passes by.
