[24] [76] For the following partial pressures of oxygen the limits are: 45 minutes at 1.6 bar (160 kPa), 120 minutes at 1.5 bar (150 kPa), 150 minutes at 1.4 bar (140 kPa), 180 minutes at 1.3 bar (130 kPa) and 210 minutes at 1.2 bar (120 kPa), but it is impossible to predict with any reliability whether or when toxicity symptoms will occur.
In Canada, a severe thunderstorm is defined as having wind gusts of greater than 90 km/h (56 mph), hail with a diameter of greater than two centimetres (0.79 in), rainfall rates of greater than 50 millimetres (2.0 in) in one hour or greater than 75 millimetres (3.0 in) in three hours, or tornadoes.

The multi-day outbreak culminated on April 27 with the most violent day of tornadic activity since the 1974 Super Outbreak. Multiple episodes of tornadic activity ensued with two waves of mesoscale convective systems in the morning hours followed by a widespread outbreak of supercells from Mississippi to North Carolina during the afternoon into ...
The four passenger GEM NEV uses 169 Wh/mi (199 mpg‑e; 10.5 kW⋅h/100 km), [28] which equates to 2.6 kWh/100 km per person when fully occupied, albeit at only 24 mph (39 km/h). The General Motors EV1 was rated in a test with a charging efficiency of 373 Wh-AC/mile or 23 kWh/100 km [ 67 ] approximately equivalent to 2.6 L/100 km (110 mpg ...
Based on ρ = 2600 kg/m 3; v = 17 km/s; and an angle of 45° Objects with a diameter less than 1 m (3.3 ft) are called meteoroids and seldom make it to the ground to become meteorites. An estimated 500 meteorites reach the surface each year, but only 5 or 6 of these typically create a weather radar signature with a strewn field large enough to ...
This was followed shortly after by the day's first severe thunderstorm watch, issued for primarily eastern Nebraska in response to a developing line of supercells. [ 15 ] [ 16 ] An hour later, the SPC upgraded some areas previously under a slight risk for severe weather to a moderate risk as a result of continuously increasing moisture content ...
12.88 mi (20.73 km) 200 yd (180 m) $40,000: Many trees were downed, with one damaging the roof of a house. This tornado tracked across some of the same area that had been hit by the Vilonia EF2 tornado the previous day. [2] [7] EF1: SSW of Stewart to NE of Tatum: Rusk, Panola, Harrison: TX
15.5 mi (24.9 km) 2,300 yd (2,100 m) A very large and damaging multiple-vortex tornado first touched down southwest of Shawnee, snapping trees and power poles, damaging or destroying outbuildings, and inflicting minor to moderate roof damage to homes and a church.
