1. Summary of basic information at 09:30 a.m. NDT.
Location: Near 42.3 North 51.7 West.
About 497 kilometres south-southeast of Cape Race.
Maximum sustained winds: 148 kilometres per hour.
Present movement: East-northeast at 76 kilometres per hour.
Minimum central pressure: 972 millibars.
2. Public weather impacts and warnings summary.
A special weather statement highlights the possibility of abnormal variations in the tides.
Any significant winds from Gert are expected to remain well offshore.
Some moisture from Gert will feed into an approaching non-tropical weather system near eastern Newfoundland. This system will reach Newfoundland on Thursday and amounts of 25 to 50 mm are forecast over portions of eastern and northern Newfoundland.
Long period swells from Gert will reach 2 to 4 metres along south-facing coastlines of Newfoundland later today, with the highest waves likely along the southern Avalon peninsula. These swells could also lead to dangerous rip currents. Significant wave heights of 3 to 5 metres are expected over the Grand Banks on this afternoon. The highest waves from Gert will remain south of Canadian waters.
In addition, Hurricane Gert may cause a series of rapid changes in water levels in harbours and inlets from the Avalon Peninsula north to Trinity Bay for a couple of hours. The most likely time ranges from late this afternoon into this evening. High tide will be occurring late this afternoon for most areas, so there is a risk for minor flooding near and after high tide.
3. Marine weather impacts and warnings summary.
The latest track for Gert has it passing over the extreme southern Grand Banks today and transitioning to a very intense mid-latitude storm as it passes east of our forecast waters. Gale to storm force winds are expected over southernmost portions of the Grand Banks, with hurricane force winds remaining just south of the Grand Banks. Gale and Storm warnings are in effect for the southern Grand Banks.
