Tropical Storm Alex

TS Alex looks good on radar and satellite this morning near the Belize/Mexico border.

The first tropical system of the Atlantic hurricane season developed late Friday off the coast of Belize and has moved inland. Heavy rain and gusty winds are occurring in Belize and along the Yucatan Coast of Mexico. A tropical storm warning was in effect in both those regions. At 9am this morning Alex was located about 170km west of Chetumal, Mexico with 40mph winds. Alex is expected to move back over the extreme southern Gulf of Mexico within the next 24 hours and could become a major hurricane by Wednesday. Models have the most likely path of the storm inland over northern Mexico near Tampico but some models carry the storm northward towards Louisiana and Texas and the BP oil disaster area. This storm has excellent structure on radar this morning and needs to be watched closely.

Heavy Rain
Meanwhile more heavy rain and thunderstorms swept across the prairies yesterday. This will be the last in a series of heavy rain events for a few days as high pressure moves in and produces very warm and dry weather this week. The heavy rain will shift east in Ontario and Quebec. A warm front will lift northward across the St. Lawrence Valley tonight with a soaking rain and some loud overnight thunderstorms. Monday will be warm and humid with thunderstorms late in the day. The middle part of the week will be unseasonably cool with some showers before a marked warming trend into next weekend. Temperatures will be25C today & 27C tomorrow in Montreal but struggle to reach 20C through Canada Day before we soar to near 30C next weekend.by
