Storms are beginning to come over the Rocky Mountains with a low pressure system that is entering hot dry air in Alberta. Severe thunderstorm watches have been issued for much of east central British Columbia and west central Alberta. Another area of precipitation is entering from Montana but carries no watches or warnings as yet. Strong microbursts are possible this afternoon and into the evening as the low crosses Alberta. A microburst is an intense downdraft from a thunderstorm that often causes localized wind damage and flash flooding.
